  5. EGNOS Ground Segment Development EGNOS Ground Segment is made of • Four Mission Control Centers, hosting each • a Central Processing Facilities • a Central Control Facilities, • Collecting data from 34 RIMS Sites hosting • Branch A, used for Processing • Branch B, used for integrity checks • Branch C, to track specific GPS satellite failure modes • Feeding Six Land Earth Stations • Broadcasting EGNOS Messages to users via 3 GEO Satellites • All interconnected via real-time digital network

  11. EGNOS Key Challenges • Ensure ionosphere (GIVE) and GPS integrity (UDRE) for a 15 years operational scenario, and still provide adequate availability (99%) and continuity (8x10-5/150 sec); • EGNOS SBAS formal certification for Safety of Life (institutional and technical issue); • EGNOS to penetrate in a large number of multi-modal markets reducing the time to service of Galileo; • EGNOS evolution after EGNOS V1 (service extension and GPS modernisation); • EGNOS and Galileo technical and service provision integration.

  12. EGNOS is intended for multi-modal applications • EGNOS/SISNET for public bus transportation(NAVOCAP, France; and also GMV, Spain) • EGNOS dissemination through FM RDS in cars (TDF, France) • EUROCOPTER (Helicopter Emergency Medical Services, Germany/France) • EGNOS to support Precision Farming (Booz Allen, UK) • DELTA hybridationtest in airports (M3 systems, France, and also at Sweden) • EGNOS disseminations through DAB radios (BOSCH/ BLAUPUNKT, Germany) • Internet EGNOS transmission: SISNET Pocket PC PDA receiver (Finish Geodetic Institute, Finland) • EGNOS/SISNET to support blind pedestrian (GMV and ONCE Spain).

  14. The deployment of the EGNOS infrastructureis close to complete • All 4 Master Control Centres (MCC) have been deployed; • All Navigation Land Earth Stations; (NLES) have been deployed; • 30 of the 34 RIMS are today deployed; • All 3 EGNOS Geostationary satellites are transmitting successfully; • EGNOS transmission/performances since Dec. 2003. Daily transmissions since July 2004. • EGNOS final functional/performance qualification planned end 2004. • ESA. ESA Receiver Workshop Conclusions. Paris 3.7.2003

  15. EGNOS Measured Accuracies Sept 5, 2004 (24h) To be noted: Less than 1 m horizontal accuracies recorded in EGNOS quite often; Excellent vertical accuracies 1-2m (well below the 7.6 m specification)

  16. Service availability measured in ESA/ESTEC (NL) Sept 20, 2004 (26 out of 34 RIMS used)

  17. Service Coverage Sept 5, 2004 (24h) (with 26 RIMS out of 34)

  19. In parallel to the start of EGNOS operations, EGNOS needs to respond positively to the dynamic GNSS environment • EGNOS AOC is based on a MRD Document developed in 1998. This allows EGNOS V1 service provision in 2004 with excellent performances. • Since then, the GNSS environment has changed significantly: • Galileo programme • GPS Modernisation program (IIR-M, IIF) • New L1/L5 GEOs • Export opportunities for SBAS technology • GPS/SBAS L5 standardisation work • WAAS FOC program launched • EGNOS V2 concept

  20. Combined Services

  21. Three EGNOS V2 versions conceived in 2005-2008 STEP 2 STEP 1

  22. Proposed EGNOS V2 core Infrastructure Evolution Plan focuses on user-beneficial functional evolutions STEP 2 STEP 1

  23. INterface System for the Provision In Real time of the EGNOS product (INSPIRE)

  24. Feasibility Analsyis EGNOS extension in Africa (ISA System)

  26. Summary • EGNOS is the European SBAS and a first step towards GALILEO, the European SATNAV constellation. • EGNOS AOC (EGNOS V1) is close to conclusion. EGNOS Initial performances are very good, with accuracies 1-2m and good APV availabilities • Almost Continuous transmission since July 2004 for the three EGNOS GEOs; formal EGNOS qualification end 2004, delivering a very valuable service to users • In parallel to operations and without any operational interruption, EGNOS will keep modernising and improving services in 2004/2008 (EGNOS V2), in response to new identified needs (e.g. Galileo and GPS modernisation, service extension). • Step I of this modernisation (2004-2005) has been approved. This includes the release of EGNOS V2.1 early 2006, with 2 main new missions: service extension (south/east) and non-GEO service multi-modal provision (INSPIRE). • Step 2, to be confirmed in 2005, includes EGNOS extension in Africa (2007) and SBAS L1/L5 services (2008).
