12 ESA/EGNOS/JV/12 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.

13 ESA/EGNOS/JV/13 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 hybridation test 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).

15 ESA/EGNOS/JV/15 The deployment of the EGNOS infrastructure is 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 Daily transmissions since July  EGNOS final functional/performance qualification planned end ESA.

20 ESA/EGNOS/JV/20 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 This allows EGNOS V1 service provision in 2004 with excellent performances.  Since then, the GNSS environment has changed significantly: 1.Galileo programme 2.GPS Modernisation program (IIR-M, IIF) 3.New L1/L5 GEOs 4.Export opportunities for SBAS technology 5.GPS/SBAS L5 standardisation work 6.WAAS FOC program launched  EGNOS V2 concept

22 ESA/EGNOS/JV/22 Three EGNOS V2 versions conceived in EGNOS V2.1 end 2005 EGNOS V2.2 end 2007 EGNOS V2.3 end 2008 STEP 1 STEP 2

23 ESA/EGNOS/JV/23 Proposed EGNOS V2 core Infrastructure Evolution Plan focuses on user-beneficial functional evolutions EGNOS V2.1 in 2006 EGNOS V2.2 in 2007 EGNOS V2.3 in 2008 EGNOS products over non-GEO data links (INSPIRE) Extension to MEDA and East of Europe Other issues (MT0/2, Standard necessary adaptations) EGNOS MT 28 Extension in Africa Modernised RIMS receivers SAR return link L5 standards and L5 GEO broadcast GNSS “sole service” using combined EGNOS/GALILEO L1/L5/Galileo (TBC) enhanced RIMS receivers STEP 1 STEP 2

28 ESA/EGNOS/JV/28 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 ( ) 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).
