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’

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

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.
