Slide 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).

Summary Slide 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. 2003. Daily transmissions since July 2004. EGNOS final functional/performance qualification planned end 2004. 1.ESA. ESA Receiver Workshop Conclusions.

Why? What? When? Summary Slide 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 1998. 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 Slide 21 ESA/EGNOS/JV/21 Combined Services Slide 22 ESA/EGNOS/JV/22 Three EGNOS V2 versions conceived in 2005-2008 EGNOS V2.1 end 2005 EGNOS V2.2 end 2007 EGNOS V2.3 end 2008 STEP 1 STEP 2 Slide 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 Slide 24 ESA/EGNOS/JV/24 INterface System for the Provision In Real time of the EGNOS product INterface System for the Provision In Real time of the EGNOS product (INSPIRE) Slide 25 ESA/EGNOS/JV/25 Slide 26 ESA/EGNOS/JV/26 Feasibility Analsyis EGNOS extension in Africa (ISA System) Slide 27 ESA/EGNOS/JV/27 Outline EGNOS System: Overview EGNOS Status and performance Summary EGNOS Evolutions. Why? What? When? Summary Slide 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 (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).
