WHAT? EGNOS S ignal I n S pace over the interNeT in real time Satellite The Internet Navigation • Ubiquitous • Ubiquitous • Standardised • Standardised • EGNOS enhances GPS • Proven communications performance to 1-2 m • Future-proofed • Very low rate needed Together, these technologies are stronger than the sum of the parts e GNSS-1 Project Office
WHY? Excellent complement to satellite transmission In urban and canyon areas. EGNOS GEO satellite EGNOS in-view EGNOS blocked by buildings Getting EGNOS corrections in these cases proves to be very useful e GNSS-1 Project Office

EGNOS EVOLUTIONS e GNSS-1 Project Office
Possible EGNOS Evolutions � Context • On-going International Standards efforts towards SBAS L5 service definition in 2004. • GEOs with L1/L5 capability will be available in Europe in 2004 • GPS modernization program: First GPS IIR-M (L2C) in 2003. 50% constellation in 2006. First GPS IIF (L5) in 2005. • WAAS evolution plans � Possible EGNOS Evolution Objectives • 1) Expansion of EGNOS Service coverage; • 2) Introduction of SBAS L5 Broadcast service. • 3) Longer term Integration of GNSS services (SBAS / Galileo) towards sole mean • 4) Provision of service through other Broadcasting means (e.g. SISNET) e GNSS-1 Project Office
In response to the new Mission Requirements EGNOS V2 (2005/ 2008) could … (I) � Incorporate additional Expansion and Interoperability message • Type 28 as done by WAAS/MSAS. � Provide SBAS service on L1 and L5 frequencies • full robustness to L1 loss/interference � Include additional RIMS • for Service coverage expansion area � Include additional GEOs e GNSS-1 Project Office
In response to the new Mission Requirements EGNOS V2 (2005/ 2008) could …(II) � Adapt Ranging Stations to GPS L2C • further robustness to interference, iono scintillation and improved coverage � Provide additional EGNOS services • provision through non-GEO means � Be implemented gradually • without EGNOS service interruption. e GNSS-1 Project Office
Service Coverage Extensions � Thanks to built-in expansion capabilities, EU Accession EGNOS service can easily expand coverage MEDA area via simple addition AFI of extra Monitoring Stations e GNSS-1 Project Office
