3 ACTIVITY DESCRIPTIONS 1 Reference: Definition of Multi-Constellation Regional System Title: Today’s Satellite-Based Augmentation Services (SBAS) such as EGNOS, augment GPS through the broadcasting of corrections, ionosphere model and associated integrity data through transparent transponders embarked on geostationary satellites. Data format and performance adheres to civil aviation standards. The current SBAS services are a very efficient means to provide augmentation services to civil aviation. The utility of those services has also been demonstrated to other user communities however as a result of studies carried out under the EC FP6 and the ESA EGNOS Evolutions Studies carried out in the frame of the GNSS Support Programme, the need for an evolution of the current SBAS concept towards a wider mission multi-constellation regional systems (MRS) has emerged. The MRS system would provide regional augmentation services (integrity, higher accuracy) to all the constellations in view (GPS, Galileo, GLONASS,…). A variety of products and dissemination means would be foreseen in order to customize the services to the needs and standards of the users. Broadcast would include in addition to GEO L1 or L5 channels other possible transmission means (i.e. GPS integrity dissemination by Galileo). The outcome of this study will be the: - Consolidation of the MRS mission and architecture definition - Assessment of the performance and mission benefits for both system operators and the user community (in close cooperation with standardisation bodies e.g. Eurocae), - Definition of a development plan and cost assessment for its deployment and operations (considering reuse of Galileo and EGNOS elements), - Definition of a test bed prototype (based on the use of SPEED – defined in a related work-plan activity) allowing a proof of concept activity in an engineering platform. The MRS study shall also consolidate the definition and development of the EGNOS next generation reference stations and of the new generative-type of payload to support EGNOS evolutions Deliverables: Study Reports 2 3 Current TRL: Target Application Need / Date: 2010 TRL: Application / Navigation Contract duration 1 Mission: (years): No T-8055 SW Clause: Dossier0 Ref.: Consistency with Harmonisation N/A Roadmap and Conclusions

3 Reference: Future Satellite Navigation System Architecture Title: The main objective for this study is to conduct the necessary system level activities in preparation of the evolution of the European GNSS infrastructure beyond EGNOS and Galileo, targeting a time frame from 2020 onwards. This study will be complemented by the dedicated studies on a Multi-Constellation Regional System and the Assessment on the use of C-band for GNSS described in separate procurement proposals. This activity will define the most important “system directions” for the European GNSS infrastructure taking into account the following aspects: • Evolution of user requirements, • Evolution of the capabilities and performance currently offered by European GNSS system on space and on-ground including functionalities such as inter-satellite link, increased spacecraft autonomy, improved navigation and integrity algorithms, etc. • Frequency allocation and interoperability with other GNSS, systems, going beyond the usage of the Lband and considering other bands such as C-band, S-band, etc. Besides aiming to improve the functionalities and performance of the current European GNSS systems, the studies shall take into account cost related aspects, aiming to improvements in the technology that are not an end in itself but justified by reduction of operational costs. Once established and agreed the “system directions” defined in the first part of the study, the work will focus on the definition of preliminary system architecture(s) of the European GNSS system for the 2020 timeframe and beyond. The work on the system architectures definition will be supported by simulation and possibly early breadboarding activities to support justification of the retained choices and the associated feasibility.

5 Reference: Assessment of the Use of C-band for GNSS Title: Although not considered for the first generation of European Galileo satellites, the use of C-Band frequencies for a user-navigation downlink may be taken into account for a future generation GNSS. For this reason, a frequency band of 20 MHz bandwidth (5,010–5,030 MHz) has been already allocated by ITU since 2000 and several European frequency filings already exist. However, on the meantime, other users have emerged who are interested in the use of the band but with incompatible requirements with GNSS. Therefore, it is becoming urgent to revisit the assessment on the viability of this frequency band for satellite navigation. The use of C-Band navigation signals offers both advantages and drawbacks. One example is the ionospheric path delay which is inversely proportional to the (squared) carrier frequency and is therefore significantly smaller at C-Band. On the other hand, the use of C-Band frequencies results in increased attenuation effects such as free space loss or rainfall attenuation, but also higher antenna directivity. A thorough analysis is necessary before defining possible services which could benefit from the usage of C-Band together with a topology for the transmission scheme (continuous transmission, beam hopping, synchronous and asynchronous transmission, satellite constellation topology, global or local coverage etc.). This activity shall define an architecture for the provision of an attractive GNSS service in C-band together with an assessment of performance and identification of critical technology both at space segment and user segment level. Special attention shall be paid to the optimization of the signal.

7 Assessment of C-band Satellite-to-Indoor Propagation and Shadowing by Vegetation Indoor positioning and navigation have become one of the driving issues for new applications in present and future positioning and navigation systems. The propagation in indoor environments at L- and in particular at C- band is the most critical element for GNSS system design due to large attenuation and multipath. In C- band the attenuation is expected to be larger than in L-band but the delay spread is longer, therefore, it is important to gain a complete understanding of the channel. On the other hand, at Cband, the electrical wavelength has a size of the same order as the leaves of the trees causing strong scattering on electromagnetic waves. This effect results in strong shadowing which is expected to be around twice as much as in L-band. Shadowing by vegetation is identified a priori as one of the major propagation impairments at C-band. The activity covers the planning and execution of a measurement campaign (using a suitable channel sounder on a flying platform) to acquire experimental propagation data, reviewing existing data and models and developing a simple statistical wideband and narrowband channel model allowing to predict the effects of the satellite-to-indoor channel and the shadowing by vegetation at C-band. The model shall be useful for design of system, devices and impairment mitigation techniques. Some preliminary assessment of the land mobile satellite channel shall be covered.

8a Reference: Study and Modelling of Ionospheric Propagation Impariments at C-band Title: The Ionospheric propagation delay at L-band is one of the largest errors for single frequency receivers in GNSS. Nevertheless, such delay is dispersive which allows the possibility to eliminate it when using two frequencies. At C-band, the ionospheric group delay is one order of magnitude smaller than at L-band. New frequency combinations between L-band and C-band might reduce the residual errors of the navigation solutions. Ionospheric scintillations which affect receiver performance and at this stage the frequency scaling form L- to C-band has not been yet fully verified and validated.

12 Development of Breadboard for Generative Payload for Regional Navigation Servcies to Support EGNOS Evolutions Satellite-based augmentation systems (SBAS) such as EGNOS currently based on the use of transparent transponders would benefit significantly from a generative payload concept because the drastically simplified up-link stations and the capability to implement secure up-links. The overall payload performance and the validation of the apportionment of specifications at unit level need to be validated. This validation requires early breadboarding and test of a representative payload prototype. The activity will include the design, manufacturing and test of an electrically representative end-to-end breadboard of a 2nd generation EGNOS payload . Re-use of existing European payload equipments from EGNOS and Galileo will be encouraged adapting it as required to the specifications of this new generative payload.

15 Reference: Narrow-Band Laser Diode for Optically Pumped On-Board Cs Clock Title: Optically-pumped Cs clock technology is an attractive alternative technology to Hydrogen Maser that naturally provides extremely high long-term frequency stability (beyond one day) offering higher spacecraft autonomy for critical services. The feasibility of the optically-pumped Cs clock technology is being established in the frame of an ongoing feasibility study (RES-PSN/06.531/CH/bg). This study has identified the laser diodes as critical components since there are no devices available today meeting the demanding requirements of spectral purity, low ageing and compatible with space environment. The availability of such devices is therefore a fundamental pre-requisite for the development of the optically-pumped Cs clock. Under this activity, laser diodes and associated critical components shall be developed, based on the specifications defined under the on-going feasibility study. Devices manufacturing, processing and packaging shall be defined and validated on a representative number of devices.

19 Reference: Galileo Signal Assessment in Real Environment Title: Performance of the Galileo Signals and its foreseen evolutions (MBOC etc.) have been assessed extensively in theory but very few real measurements have been done in order to complete the characterisation and moreover not in all the possible user environments, and this mainly because of the lack of hardware electrically generating and receiving the signal. In particular multipath and interference are very difficult to be studied by analysis and simulation only, and require extensive test campaigns in order to realistically characterize the receiver behaviour and performance. This specific study is supposed to complement the current available performance assessment with results from test campaigns based on an electrically generated signal in the field (e.g. GIOVE signal), or in a realistically simulated environment (e.g. GSVF constellation simulator) and to confirm or extend current knowledge on Galileo Signal and receiver.

21 Consolidation of Inter-Satellite Sub-System for GNSS Orbit Determination and Time Synchromization The on-going system activities (ref. EGEP, GSP programmes) are indicating a very significant improvement in the system navigation performance figures thanks to the introduction of the inter-satellite ranging & inter-satellite communication-links. At the same time the on-going activities are identifying the critical technologies necessary to enable these enhanced capabilities mentioned above (both at space segment and at ground segment level). Although the feasibility of the critical technologies is also being assessed within the ongoing activities, a consolidation from both technology perspective is mandatory, mostly for the inter-satellite ranging & inter-satellite communication-links on-board sub-systems. This consolidation is required to investigate to further reduce the power, mass, and volume of this critical unit, and is possible thanks to the fact that present specification includes very significant margins. The activity will trade-off inter-satellite ranging & inter-satellite communication-links on-board sub-systems complexity versus orbit and clock prediction algorithm performances. The orbit and clock prediction algorithms have been already addressed in the related studies and will be an input to this activity. Deliverables: Reference: Title:

Reference: Title:
24 GNSS Open Signal Spoofing Issues
Spoofing is a technique by which a wrong GNSS positioning is generating by feeding fake GNSS signals to a receiver. Several measures exists to protect users against the threat of spoofing including satellite navigation signal authentication, external augmentation services or the use of complementary sensors on the receivers. The purpose of this activity is to assess the practical threat posed by spoofing so that adequate countermeasures can be studied and defined in separate activities of the programme. In particular, the case of low cost spoofers, involving low or medium complexity, will be addressed. Following an analysis of the weaknesses of the current signal/message for the existing and planned Galileo and GPS open signals, the activity will include the prototyping of the signal generation and the receiver chains with a view to analyze the spoofing threat. The study will conclude with recommendations on practical ways to protect against spoofing. Security aspects for the protection of information will be taken into account in the undertaking of this activity. Deliverables: Study report. Simulation results, GNSS spoofing laboratory test-bed. 2 3 Current TRL: Target Application Need / Date: 2011 TRL: Application / Navigation Contract duration 1.5 Mission: (years): No T-8377 SW Clause: Dossier0 Ref.: Consistency with Harmonisation n/a Roadmap and Conclusions

25 Reference: Use of C-band for GNSS-Reflectometry Title: GNSS-Reflectometry is a new technique based on the use of the reflected GNSS signals in the surface of the Earth, i.e. the sea surface for earth observation applications. Today it is realized on the use of existing and planned L-band navigation signals only from GPS, Galileo and other constellations. The use of C band satellite navigation signals for GNSS-R application has the potential for improvement of mesoscale altimetry accuracy because can assit in reducing the errors induced by the ionospherem and the sea surface roughness. The combination of L- and C-bands leads to a much smaller error amplification factor, with the result that it is not neccesary to apply ionospheric spatial filtering as currently proposed for this application. This will lead to a better removal of the excess path delay. Moreover, independent C-band and L-band observations will allow reducing the speckle and hence improving the altimetric precision. C-band will also bring benefits to wind retrieval measurements since C-band is the frequency of choice for current wind scatteromters. Moreover, C-band will also assisst in the determination of the ionospheric Total Electronic content as a direct by-product of the altimetry application. This study will look at benefits of C-band for both ice and land in terms of determining ice-free board and soil-moisture. Models and simulations currently available for the L-band only instrument will be extended to the use of C-band.

26 Reference: EGNOS V3 Definition Phase Title: EGNOS provides today an augmentation service to GPS L1 allowing allowing European users to get improve accuracy and integrity allowing civil aviation aircrafts to perform so-called APV-I precision approach operations. With the deployment of Galileo, the introduction of new capabilities in GPS and the completion or arrival of new constellations (e.g. GLONASS) , new mission and system evolutions are being considered for EGNOS to provide new or enhanced services. Moreover, current experience of EGNOS operations has allowed already to identify the need to introduce operability upgrades. Finally, the management of tehcnology obsolescence is also an issue since some elements where deployed more than 5 years ago.

27 Design and Development of Antenna Protection Structure for GNSS Reference Stations Interference and multipath at the EGNOS and Galileo Sensor Stations are of major concern. Interference and multipath impact the quality and availability of the output of Sensor Stations, hereby impacting the overall GNSS performance. In this activity, a prototype construction called the Interference Local Protection (ILP) shall be developed and demonstrated. The ILP is a structure around the antenna of the Sensor Station, hereby shielding the antenna from external interference and multipath from low elevations. This structure is a geometric construction with a diameter of 1 to 3 meter , consisting of RF absorbing material. The structure has to be optimised for both interference and multipath protection, capability of tracking satellites at low elevations, and operational constraints. The ILP does not require any modifications of the Sensor Station’s antenna or receiver. In the past, at a number of EGNOS Sensor Stations structures have been installed to mitigate interference and multipath. An ongoing feasibility study indicates that the performance of these structures can be significantly improved by optimising the shape and the material used. In this activity, the ILP shall be developed and demonstrated. The ILP concept is a candidate technology to be applied for the modernization of EGNOS reference stations.

28 Reference: Application of Dual-Tracking Technique to GNSS Reference Stations Title: Interference and multipath are among the most important limitations to GNSS systems. The proposed concept called “dual tracking of signals” includes two GNSS receivers and two GNSS antennas; the gain of one antenna is optimised for tracking satellites at high elevations (e.g. > 30 degrees), the other for tracking satellites at low elevations. Each antenna is connected to its own receiver, and advanced algorithms are applied to combine measurements of both receivers to measurements of a single “virtual receiver and antenna”. As a result, using the advanced algorithms for combining data of both receivers in an optimal way: - Tracking satellites at low elevations can be optimised - The impact of multipath and interference can be minimized This activity includes the whole process of design, development and / or integration of HW and SW, and demonstration of the benefits of the dual-tracking antennas concept for Sensor Stations, an in particular for the modernization of the EGNOS reference stations.

29 Design and Development of Interference Monitor System for GNSS Reference Stations In the current GNSS design, a full analysis of the interference environment is performed before the start of operations of a sensor station only. However, as the GNSS Frequency-bands are shared with other users, the interference environment cannot be assumed to be constant. In the current design of the EGNOS and Galileo systems, real-time interference detection can be performed indirectly only (i.e. by assessing the impact on sensor station observables), however that is not adequate for concluding whether there are or there are not interference issues to be solved at one site. In this activity, a real-time Interference Monitor System for GNSS Reference Stations shall be developped. This system shall provide the GNSS Operator in real-time the following information per Reference Station: 1) Spectra (In-band and Out-band) 2) Characterisation of interference in the time domain 3) Expected impact of interference on Reference Station output 4) Type of interferer Furthermore, the system shall store and allow retrieval of data for anomaly research, and provide statistical information per Reference Station. The system shall consist of: -- Local elements (equipment located at the Reference Stations) -- A central element (located at the GNSS Operator Premise) The local elements are expected to contain per Reference Station one or several Spectrum Analysers and Antennas. Alternatively, instead of Spectrum Analyser(s), upgraded GNSS Receivers may be used. The central element shall consist of a server. Using the input of the Local Elements, the Central Element shall provide the functionality 1) to 4) listed above.

31 Reference: Design and Development of On-Board Integrity Monitoring Unit Title: Integrity monitoring is currently provided with the usage of a complex ground infrastructure which is not only expensive but also affected by all the propagation/geometric/network effects and so sometimes not sufficiently accurate. Proper calibrated equipment can be included on board to measure the signal at the radio-frequency output of the payload providing instantaneous and accurate detection of specific failure modes. The satellite failure probability can be drastically reduced if not made negligible thus reducing the need for a complex ground infrastructure. This activity will be split in two phases: - Design phase: funder under TRP (ref. T606-007ET). Budget: 300 K - Implementation and testing phase in a payload test-bed: funded under EGEP. Budget: 1500 K For the testing phase, the re-use of the GIOVE-B Engineering payload set-up available at ESTEC is planned.

34 Reference: Development of Navigation Payload Sef-Equalization Sub-System Title: The self equalized payload implements the compensation of linear (amplitude, group delay) and non linear distortions of the navigation signals. The technique is based in the sampling of the navigation signal close to the satellite navigation antenna and its comparison with the ideal signal. The difference between the two is "equalized" by adequate predistorsion in the signal generation. This allows to compensate the overall transmission chain impairments (signal generator, pre-HPA filters, HPAs, OMUX,…), including temperature and ageing stabilities. By doing this, it is possible to improve system level key performance ( tracking bias, correlation loss, code-carrier coherence,…) required to improve navigation accuracy to submeter level. The technique has been already studied in detail the frame of the "Advanced Self-Equalization Concept for Navigation Payload", Contract no. 21439, a previous activity of the programme. Two variants of such technique can be considered: 1) Closing the compensation loop on-ground. In this case the samples taken of the transmitted signal and sent to ground via the satellite TC/TM link where the comparison with the ideal signal is performed and the required pre-distortion determined. 2) Closing the compensation looop on-board by direct comparison of the sampled signalvwth the payload signal generation unit output. This activity will include the development of the units required for both approaches and its testing in an advanced navigation payload test-bed. The re-use of the GIOVE-B EM payload set-up available at ESTEC is planned.

35 Reference: Ionospheric Monitoring Experimentation Plan and Instrument Development Title: The development of Global Navigation Satellite Systems (GNSS) with safety of life services, such as Galileo, has shown that radionavigation signal propagation impairments due to the ionosphere are key drivers of system performance. Current systems are based on ionospheric models and data for nominal averaged situations, however, extreme cases which happen more often during solar maximum years have not been understood completely and therefore the effects on GNSS under those situations is not fully characterised. Ionospheric modelling is a challenging domain, depending on solar activity and its interactions with geomagnetic field; the ionosphere may deviate from its nominal behaviour. This happens, for instance, during severe geomagnetic storms. In those cases, it is essential for a safety of life system to confirm that the integrity of the computed corrections is still maintained while minimising the impact on availability and continuity of service. For this reason, accurate models or realistic synthetic/measured data of a disturbed ionosphere is needed for a complete qualification. Ionospheric amplitude and phase scintillations are important ionospheric impairments on GNSS signals affecting system performance for user receivers, but also for Sensor Stations in the ground segment of the GNSS system. Strong scintillations can induce cycle slips and loss-of-lock in GNSS receivers. Scintillations depend on location, time-of-day and solar activity. Also large spatial and temporal gradients of electron density are observed in low latitude regions and they may impact the performance of safety-of-life carrier smoothing receivers . The activity includes preparatory tasks for an ionospheric monitoring during solar maximum including: review of state of the art, analysis of experimental requirements, ionospheric parameters to be analysed, instruments, consolidation of calibration and processing algorithms, experimental plan, analysis of optimal measurements sites. For the sake of efficiency, re-use of existing infrastructure and sites (i.e. GIOVE mission segment, national agencies, IGS) shall be foreseen whenever possible. The actual infrastructure development, deployment and ionospheric monitoring is planned to be done as part of a separate procurement coordinated with this development. The activity will also include the design and development of ionospheric scintillation instruments based on Galileo signals. Specific developments of semi-codeless tracking GPS receivers for ionospheric scintillation monitoring have been done in the past, which can provide very useful information for nominal scintillation levels, however they are far from robust under strong scintillation activity, not being able to derive enough statistics under extreme cases, which is needed for stringent Integrity and Continuity GNSS requirements. Those receivers have very specific characteristics regarding sampling rate and loops filter bandwidth in order to cope with scintillation without altering the results. The possibility to use codes on signals at various frequencies in Galileo, together with other signal characteristics (C/No, bandwidth, code length, pilot signals, ...) will allow to design a robust receiver for ionospheric monitoring. The receiver should be able to provide also accurate STEC measurements, together with a good estimation of Noise and Multipath. The receiver shall comprise the complete chain, from antenna to digital processing and data processing for ionospheric parameters and regular observables. No major specific new development is foreseen for any of the hardware components, but instead a thorough optimisation of existing architectures taking into account specific requirements. Five ionospheric monitors shall be developed: 1 prototype plus 4 operational.

41 Definition of In-orbit technology demonstration for GNSS Evolutions
In the EGEP frame, several system concepts and technologies are investigated for the future generations of the European GNSS systems, EGNOS and Galileo. This is leading to the definition of GNSS systems evolutionary features. However, before deciding on the implementation within the later generations of these systems, demonstrations may be necessary, depending on the actual innovation and maturity of the considered features. For some features, demonstrations can be performed in laboratories on ground or via simulation. Demonstration of other features can only be done in orbit, with environmental, operational, and performance scenarios as close as possible to those of the future navigation systems. The project will be developed along the following tasks: -
Review and consideration of the outcomes of (1) the completed EGEP development activities on system concepts and technologies, e.g. space clocks (mini-Passive H-Maser, Cesium), robust Clock Monitoring and Control Unit, self-equalizing P/L, C-band P/L, and (2) results from current activities the results of which are expected by mid 2010 (i.e available before the launch of the ITT), including activities related to advanced P/L techniques, Inter-Satellite Links, On-Board Integrity Monitoring Unit.
-
Investigation and identification of flight opportunities in the near term, suitable for the demonstration of the above concepts and technologies.
-
Definition of mission requirements and constraint scenarios for the demonstration of concepts and technologies.
-
Definition of possibilities for associated demonstration system concepts, and related preliminary overall project plans.
-
Mapping of the results of this activity into mission requirements and constraints, and possible system concepts addressing them.
All the project tasks will be carried out keeping in mind representative environmental, operational, and performance aspects.

42 Study (1) of the Use of Galileo Integrity Products to Support Advanced RAIM Concepts
Advanced Receiver Autonomous Monitoring (ARAIM) techniques are currently receiving significant attention due to the prospects of good performance when applied to the case of many satellites with very good signal quality, as will be the case of Galileo. It is hence interesting to analyze how the current Galileo system could support ARAIM techniques using the integrity data already foreseen to be provided by the system, such as the Signal in Space Accuracy (SISA). In this study, several ARAIM algorithms should be defined starting from a comprehensive review of the literature already existing on the subject. Of particular relevance is the suitability of the algorithms to meet aviation LPV-200 performance requirements and the capability of the algorithm to be adapted to the use of the existing Galileo products without major modifications. The study shall include an analysis of the complexity of computing similar products for GPS by adding extra functionality to the currently foreseen Galileo and/or EGNOS infrastructures. The implications in the EGNOS and Galileo systems (ground segment, signal messages) and a review of integrity allocations between ground, space and user segment when using the selected algorithms shall be undertaken.

45 Definition of in-orbit RF interference monitoring mission in the navigation band GNSS signals are vulnerable to man-made and natural sources of radio frequency interference (RFI) and therefore not immune from disruptions. Types of interference can be classified into: - Intentional and unintentional in-band transmission as a consequence of a heavily congested L-band, - Out-of-band interference of higher harmonics of signal modulations, - Solar activity resulting in scintillation, - Satellite anomalies which could be detected by the GNSS Control Segment. Reference: Title:
Since the amount of interferences continues to increase, one of the main challenges of the future will be to detect its sources, to identify and to locate them, and to inform an appropriate GNSS centre about them. The continuous monitoring of the RF environment together with the appropriate analyses and subsequent actions to guarantee a minimum or even no signal outages at all, becomes therefore an issue of extreme significance. Since the installations of RFI detection systems on selected stations on earth can be considered only as a very local solution and the alternative, the use of such systems in dedicated aircrafts, appears very expensive, it is the the objective of this activity to investigate the feasibility of detecting and localizing interference sources in the RNSS bands with an appropriate system flown on a small LEO satellite (in-orbit demonstrator). Other possible flight opportunities (e.g. ISS) shall be discussed as well. Based on RNSS user requirements the definition of a payload and concepts for a RFI satellite mission shall be studied, including proposals for analyses, reporting and information to the GNSS users. The activity shall further include the development of a mission simulator to trade-off different mission scenarios. A programmatic dossier including among other elements development plans, with emphasis on enabling technology roadmaps, and cost estimates shall also be established. Deliverables: Design report, mission simulator covering: a) Feasibility assessment of the in-orbit monitoring, localization, identification and analyses of RF interference. b) Mission study (including preliminary orbit design) and engineering design of the payload. c) Identification of the resources needed by the platform (e.g. power, data rate, downlink requirements, electromagnetic cleanliness, etc.) and of the operational profile (pointing knowledge/accuracy, etc.). c) Mission simulator to trade-off among several settings of the basic mission and instrument parameters.

Under the on-going contract #21674 (part of European GNSS Evolutions Programme), a miniaturized PHM is being investigated, focussing mainly on the miniaturization of the Physics Package, which is the most bulky and heavy sub-system. Very promising results have been obtained, showing no degradation of performances in a package reduced by more than 30%. In parallel, new electronics designs are being investigated and will be validated with the miniaturized Physics Package. This activity is a follow-up to the above mentioned contract and aims at consolidating the electronics able to supply and accomodate the miniaturized PHM, and to validate the fully integrated miniaturized PHM clock at EM level. This activity shall start with a review of the main results of the the above mentioned contract and the identification of limiting factors. The Physics Package shall be updated as neccessary and the Electronics Package design shall be completed and validated. The two sub-systems shall then be assembled, integrated and tested in a representative environment. The use of the GNSS Payload Testbed available at ESTEC is planned to further validate the design.

47 Design, Development and Validation of Robust RAFS
Lessons learnt from GIOVE experimentation shows that the current Rubidium Atomic Frequency Standard (RAFS) technology is subject to non-monotonous frequency drift variations (frequency jumps, frequency changes...) that detrimentally affect the navigation (in degraded scenarios) and integrity performances. A number of possible causes for such behaviour have been identified to be micro-vibration, thermo-mechanical stress release, power shift or injection pulling effects. In parallel, GPS literature indicates that such behaviour is also visible in some of their RAFS clocks, but at a much lower level (factor ~10) and at a much lower rate of occurence. Another limitation of RAFS technology was identified in September 2009, when one of its most important electronics components (FPGA) became subject to export license control under ITAR. This activity shall first focus on the review and analysis of the RAFS design in order to consolidate the identification of current limitations (e.g. phase/frequency changes and jumps, FPGA-based synthesizer) and possible solutions. Secondly, the identified solutions shall be developped and validated at sub-assembly level. Finally, all solutions shall be implemented in an EM representative unit that shall be subject to an extensive test and validation campaign, in particular in terms of environment (e.g. microvibrations). The use of the GNSS Paylaod Testbed available at ESTEC is planned to further validate the design update.

Title:
Galileo System Simulation Facility Upgrade for GNSS Evolutions
The Galileo System Simulation Facility (GSSF) is a software simulator tool that reproduces the functional and performance behaviour of the Galileo system. The Service Volume Simulation (SVS) capability of the GSSF allows analysing the navigation and integrity performance over longer periods of time and over large geographical areas. The GSSF allows the user to assess all relevant Figures of Merit on global or regional grids or for individual positions. In addition to the Figures of Merit used to analyze the Galileo performance vs. the current system requirements, the functional flexibility of the GSSF makes it suitable to support new system simulation capabilities. One of the strong points of the GSSF is also the high level of validation. The GSSF has undergone an intense validation campaign during which the SVS function was compared against COTS software (e.g. STK, Polaris) or independent industry simulators implementing the Galileo specific algorithms (such as the integrity algorithm). As a result the GSSF achieved a high level of validation and is the trusted simulation tool for the Galileo Project performance analysis. A number of system studies were recently completed in the framework of the EGEP addressing future satellite navigation architectures with new features, that presently are not impemented in the GSSF. These features include inter-satellite ranging, multi-constellation SBAS augmentations or C-band navigation downlink signals. Through other activities of the EGEP, the use of Advanced RAIM techniques will also be investigated with the review of existing and defintion of new algorithms. The objectives of the this activity (ID-49) are to include these new capabilities in the GSSF to provide the Agency with an updated tool to support the neccesary system level activities which will be required in the near term to support standardization activities, international discussions and system evolutons analysis and definition in general. The Executive intends to place a frame contract with the developer of the GSSF. The frame contract will be activated in the form of specific work orders to be defined by the Agency. The work orders will in detail define the capabilities to be included in the GSSF.

50 Development of Advanced Multi-Constellation Signal Testbed
There are in the Agency several multi-constellation signal simulations tools available, covering the signals from GPS, GLONASS and Galileo as they were defined at the time of developing or procuring these tools. Following the completion of a number of system studies on possible future GNSS missions (Cband, S-band) new type of signals have been defined that are proposed to be considered in future generations of GNSS. These types of signals consider innovative aspects, such as new modulations which are not supported by the current simulators. Moreover, as the work progresses on the refinement of these new signals, there will be a need to incorporate those features in the simulators, which will require enhanced flexibility in the architectures of the simulators. The Advanced Multi-Constellation Signal Testbed will be used by the Agency to support further studies on the definition of future GNSS signals. The testbed will also be used as a complement to the exisiting tools used for radio-frequency compatibility analyses between Galileo and other GNSS.

51 GNSS-R Feasibility Study (Phase A)
GNSS signals (e.g. from GPS or Galileo) can be used for remote sensing as they are reflected off the Earth's surface – so-called GNSS Reflectometry (GNSS-R), following the passive interferometry principle of the PARIS technique initiated by ESA. Where these signals are collected over the ocean they contain information on the significant wave height (SWH) which is largely dependent on wind speed. Over ice, the roughness and hence the ice-age may be determined and over land, the signal can be used to determine soil moisture. In addition, the technique may also be used for ocean altimetry. Unlike the GNSS-R scatterometry type applications, which rely on the instrument correlating the reflected signals with on-board generated code replicas, the proposed GNSS-R instrument uses a codeless technique whereby the signals received with an upward looking antenna are correlated with their reflections over ocean or ice and pick-up with a downward looking antenna mounted on the same satellite. The technique does not require acquisition/tracking of the signal modulating codes. The Agency has already initiated a proof-of-concept activity under TRP to examine the practicalities of this technique (C22592). This study is still on-going and the results it produces will be fed into the GNSS-R Feasibility Study (Phase A), which will be organized in three steps: 1. Identification of end user requirements and their translation into observation requirements and further into technical requirements. System concepts including all elements of the mission architecture will be identified: space, ground, orbit, satellite, platform and payload, and with due consideration to launcher opportunities. Each concept will be characterised with emphasis on the elements affecting performance and cost. Analysis and performance simulations will be conducted. At a Preliminary Concept review (PCR) a baseline will be selected in consultation with the final users. This baseline shall provide sufficient performance to demonstrate Galileo potential and is compatible with programmatic constraints. 2. Detailed definition of the selected baseline with emphasis on the instrument including architecture, antennas, beam-forming network, down-converter, correlators, processor and receiver. The definition will also include aspects related to the principal satellite platform systems such as the AOCS and outline of the data processing flow. Technology development plans will be established. The step will be completed with a Preliminary Requirements Review (PRR). 3. Refinement of the mission development plan and its costs.

52 GNSS-R Simulator Framework Development
GNSS signals captured by a satellite in low Earth orbit after refraction through the atmosphere or reflexion by the Earth surface allow measurements of important scientific geophysical parameters. The proposed activity will define a simulation framework for the scientific analyses of reflected signals. It will be able to integrate models of targets, e.g. land, ocean, ice surface, etc. It will include ionosphere and neutral atmosphere models, orbits, platforms and receiver models, as well as data processing algorithms. It will further consider models of Galileo, GPS, GLONASS and other GNSS constellations as well as other signals of opportunity, still to be defined. The framework will provide the required simulation services, such as initialisation, configuration of inputs and outputs, start/stop, tailoring of analysis, etc. The interfaces will be specially addressed so as to be user friendly and allow focusing on the research tasks, configuration of input and output, user interfaces. The simulator will allow testing of different space systems, receivers, including software defined receivers, concepts and data processing algorithms.

53 ESA GNSS WIKI
There is already information available about satellite navigation in the free web database called Wikipedia. The principle that everybody can edit it, leads to the fact that such information is not always trustable. Over the last years the need emerged for a reliable knowledge data base to educate students, graduates and young engineers. Moreover, the availability of reliable information is for everybody working in satellite navigation required and may lead even to more efficient working. The ESA GNSS WIKI project will cover the creation of a free web-based, collaborative GNSS encyclopaedia, which will compile the acquired knowledge in GNSS, with special emphasis on Galileo and EGNOS. The aim of this tool is to become a worldwide reference for the GNSS community and universities. The ESA GNSS WIKI should employ the open editing model called "wiki". The activity will focus first on the definition of structure of the GNSS WIKI, the specific contents and the process, tools and control mechanism for its built. Then, it will proceed with a prototyping of the tool. The articles of the ESA GNSS WIKI, will be reviewed through a well established group of GNSS experts in order to ensure the highest technical standards and reliability, The ESA GNSS WIKI should be duly integrated into the global ESA Knowledge Management strategy/policy, as defined by the ESA Education Office, and follow the general rules defined for that. Finally the GNSS encyclopaedia will be put on ESA servers accessible for everybody. This knowledge-based GNSS activity will be done in close cooperation with the ESA Education Office.

ID-057 Development and Validation of Critical technologies for On-board OpticallyPumped Cs Atomic Clock for GNSS satellites Under a related activity of the European GNSS Evolutions Programme, an Elegant Breadbaord (EBB) of an on-board optically-pumped Cs clock is being developed (Contract No 21852/09), as a potential future alternative to current on-board clock technologies. The reason for this is that the Cs atomic clock would have performances and characteristics in the range between those of the current Rubidum Atomic Frequency Standard (RAFS) and the Passive Hydrogen Maser (PHM) being used in Galileo. Reference: Title:
In this activity, a number of critical key technologies have been identified that require specific development and validation in order to be at the end implemented in a fully space-representative clock. Today, only one of these critical technologies has been addressed (Laser Diodes, Contract No.21645/08, European GNSS Evolutions Programme) with the testing of the performance of the laser technology available from one European supplier. The objectives of the present activity (ID-57) is to complete the development and validation of the critical technologies required for the clock bulding based on the experience gained from the EBB development. It is in particular the intention to perform specific and independent* evaluation of the following items: Full characterization and evaluation of laser diodes from various European suppliers Characterization and validation of photodetectors Development and validation of Cs oven Development of MMICs for Cs clock synthesizer Investigations and implementation of fibred-based optical sub-system For each of these items, dedicated technology demonstrators shall be designed, manufactured and tested, and they shall be validated in specific test beds (including lifetime where relevant). It is intended to carry out this activity in parallel with the separate develpoment of the Engineering Model, so that the output of both activities can be combined in a subsequent Engineering Qualification Model (EQM) phase. *Independent evaluation from the supplier of the components will be required. Procurement approach: Direct Negotiation with RUAG (CH) as prime, with TED (F) and CSEM (CH) as subcontractors. RUAG (CH) is currently involved in the development of the optical sub-system of the EBB, involving most of the critical technologies related to this activity. They will be supported by TED (F), who is prime contractor for the overall clock development and can bring the perspective of the end user. Finally, CSEM has been involved since the beginning of the Cs clock development and has acquired extensive experience and facilities in this domain.

ID-058 Reference: Mediterranean EGNOS User Testbed Title: EGNOS is a system that provides correction and integrity data to GPS single frequency (L1) users in accordance with the standards defined by the civil aviation community for Satellite Based Augmentation Systems (SBAS). The system consists of a network of reference stations mainly deployed over the European region. Data are sent to the users through EGNOS GPS-like signals broadcast from two GEO satellites. EGNOS was developed by the Agency. Ownership of the system was transfered in March 2009 to the EC who took responsibility of the EGNOS Implementation program management within the framework of the EC GNSS programme. With the deployment and completion of new GNSS constellations, the need for addressing potential EGNOS evolutions has become apparent. New augmentation data provided by EGNOS will allow users to take maximum benefit of the new capabilities available from GPS, GALILEO, GLONASS, COMPASS, etc. To this end, the Agency has already launched in the frame of the European GNSS Evolution Programme, two parallel Phase A studies looking at a new generation of EGNOS, the so-called EGNOS-V3 to be operational by 2018. These studies are being complemented with a set of experimentation testbeds addressing different user communities to test potential new EGNOS products. This proposed Mediterranean EGNOS User Testbed (MEUTB) aims at complementing the above activities by addressing the followins aspects:
Needs of the maritime community at mid latitudes. Extension of the EGNOS coverage in the eastern Mediterranean region. Feasibility to implement authentication feature (data and/or signal) and associated benefits at user level; Possibilities to exploit the E5b signal from Galileo and EGNOS. Interoperability of EGNOS with the adjacent System for Differential Corrections and Monitoring (SDCM) that is planned to augment GLONASS.
Within this activty, an experimental network of multi-constellation reference stations shall be deployed to provide adequate coverage of the eastern Mediterranean region paying particular attention to cover areas overlapping with the coverage of SDCM. The stations shall be connected to a processing centre in charge of computing the MEUTB products. Dissemination to the users shall be done through exsiting means available to the maritimie community. The use of GEO satellites equipped with SBAS transponders will also be considered. Page 82/83 ESA Standard Document Date 29.11.2010 Issue 1 Rev 1

Different products shall be investigated within this testbed, including:
Multi-constellation multi-frequency corrections/integrity data. Additional data to authenticate the GNSS signals visible over the region.
The characterisitics of the products shall be be tailored to the needs of the maritime community in terms of performance, dissemination means and standards. An efficient use of the infrastructure deployed in the frame of the other testbeds developed in the European GNSS Evolutions Programme is foreseen as well as the use of any other infrastructure which may be available in the region and fits the purpose of the testbed.
