5 Typical User Communities
EGNOS Services Service Transmission Means Typical User Communities Guarantee of Service Open Service L1 frequency Pedestrian, in-car navigation None Safety of Life Service Aviation, maritime, railway Compliance with ICAO standards (certification) Commercial Service (EDAS) Ground network Pedestrian, in-car navigation, research (e.g. atmospheric, tectonics), high-accuracy Compliance with SLA when commercialisation will start SLA … Service Level Agreement, EDAS … EGNOS Data Access Server ‘It’s there, use it’

6 EGNOS Services – Current Status
Accuracy Service Status Expected Lifetime Open Service Typical vertical and horizontal positioning accuracy in the centre of Europe around 1m (spec: 3m horizontal, 4m vertical) SIS available, declaration of "entry into service" planned for late 2009 20 years Safety of Life Service Same accuracy as Open Service. SoL service levels compliant to ICAO SARPS definition for APV1 Test SIS available, declaration of "entry into service" planned for mid-2010 Commercial Service (EDAS) Corrections provided by terrestrial network allow for sub-meter accuracy locally or regionally through additional processing Experimental service available since 2008 SIS … Signal in Space, SARPS … Standards and Recommended Practices, SoL … Safety of Life ‘It’s there, use it’

7 EGNOS Performance (April 2007 – June 2009)
=> More than 99% availability over the last months ‘It’s there, use it’

8 EGNOS Performance (May 2009)
Note : the deployment of additional RIMS in Northern and Eastern Europe, Sourthern Europe, Northern Africa and the Middle East will increase the availability area of APV-1 APV … Approach with vertical guidance ‘It’s there, use it’

9 EGNOS Service Area EGNOS Service Area EGNOS Satellite Footprints
The European Geostationary Navigation Overlay Service (EGNOS) is Europe’s first venture into satellite navigation. It augments the two military satellite navigation systems now operating, the US GPS and Russian GLONASS systems, and makes them suitable for safety critical applications such as flying aircraft or navigating ships through narrow channels.   Consisting of three geostationary satellites and a network of ground stations, EGNOS achieves its aim by transmitting a signal containing information on the reliability and accuracy of the positioning signals sent out by the Global Positioning System (GPS) and the Global Orbiting Navigation Satellite System (GLONASS). It allows users in Europe and beyond to determine their position to within 2 metres, compared with about 20 metres for GPS and GLONASS alone. EGNOS Satellite Footprints INMARSAT AOR-E (15.5°W), ARTEMIS (21.3°E), INMARSAT IOR-W (25°E) ‘It’s there, use it’

10 EGNOS Programme Status

11 Northern & Eastern Europe
EGNOS Extensions Southern Europe/MEDA Middle-East Northern & Eastern Europe Depending on the extension area, technical implementation may vary from: Homogeneous extension with deployment of additional RIMS Regional infrastructure including additional processing capabilities ‘It’s there, use it’

12 EGNOS Service Evolutions

17 Galileo Performance Requirements (Dual Frequency)
Service Horizontal Accuracy (95%) (incl. system margins) Vertical Accuracy (95%) Availability for global coverage Integrity Open Service 4 m 8 m > 99.5% NO Commercial Service Detailed performance requirements under elaboration Safety of Life Service YES (LPV200) Public Regulated Service YES Please note: Currently the HLD still specifies for the PRS a horiz. accuracy of 6 m and a vertical accuracy of 12 m. However, this will be corrected to 4 and 8 respectively once the document is updated. Note : The expected measured performance is higher than the requirements, as is the case with EGNOS Navigation solutions powered by Europe

18 Galileo Test Satellites
Galileo Test Satellites GIOVE-A Giove-A launched on 28 December 2005 Securing of Galileo frequencies Still operating from a higher orbit Giove-B launched on 27 April 2008 First Passive Hydrogen Maser atomic clock ever flown in space Implementation of CBOC signal Working as expected GIOVE-B Navigation solutions powered by Europe | 18

19 Galileo IOV vs FOC Component IOV Phase FOC Phase Satellites 4 27(+3)
Control Centres 1 3 Mission Uplink Stations 5 9 TT&C Stations 2 Sensor Stations 20 30-40 ESA will launch the first four operational satellites using two separate launchers. The first two satellites will be placed in the first orbital plane and the second in the second orbital plane. These four satellites, plus part of the ground segment, will then be used to validate the Galileo system as a whole, using advanced system simulators. Then, the next two satellites will be launched into the third orbital plane.   Once the Galileo system has been validated, the final stage will be to build up the rest of the constellation by completing it on all its three orbital planes. This will then require several launches with Ariane-5 or Soyuz from the Europe’s Space Port in French Guyana. Galileo will then be fully operational, providing its services to a wide variety of users throughout the world.   IOV (In Orbit Validation), FOC (Full Operational Capability) Navigation solutions powered by Europe
