4. EGNOS: GPS augmentation service
EGNOS Service Area
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.

Extension to the E5a/E5b frequency decided on ARTEMIS replacement
Evolution of Standards ►long term
Standardisation of E5a and E5b, L1 CBOC on-going
Augmentation of new GNSS
Additional Services
LPV200 service level ►medium term (2011) EGNOS capability to meet this service level currently under technical evaluation
EGNOS time service ►medium term
Possible critical communication message

11. EGNOS Value Added
EGNOS
EGNOS Value Added (versus GPS)
Size of circles indicates importance of each attribute of EGNOS to the market, (large = very important)
The extent to which EGNOS meets these attributes is identified by the colour: green … meets requirements red … does not meet
Integrity may be useful to Road applications, primarily RUC, but there little awareness of the value or potential role or need for it.
Precision agriculture in OS includes crop spraying, yield management and field / plot measurement

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.

22. EU-USA Common approach with regard to an overall GNSS strategy
Solving the compatibility issues and enhancing interoperability
Developing a common GNSS standard for Safety of Life
Coordinating inputs to UN ICG/Providers’ Forum

23. EU-USA Galileo and GPS are compatible and interoperable
Thanks to detailed and lengthy bilateral discussions through Working Groups, established by the EU US 2004 Agreement and following close monitoring by the senior levels chaired by US DoS and EC
Excellent results to-date
MBOC common modulation
National Security Compatibility Compliance
GGTO implemented on IOV and tested on GIOVE
But, many more joint efforts are needed to ensure C&I for all GNSS

Further definition of « non-discriminatory approach to trade in GNSS goods and services (WTO)
Discussion on IPR aspects of Galileo R&D
Galileo spectrum in U.S. National Table of Frequency Allocations
Joint outreach (GPS-Galileo fact sheet etc)
Procurement of GPS and Galileo
Security
Sofar: Export controls, technology control
Next: Endorsement of new legal basis for exchange of classified information
Protection/hosting of ground stations
Security roles and responsibilities

26. EU-USA Safety of Life Service: common GNSS standard
1st generation SBAS (WAAS EGNOS MSAS GAGAN) has reached a good level of maturity, but are based on GPS only
Galileo has designed a SoL standard
Integrity concepts likely to evolve with increasing number of constellations
Other constellations are interested in developing built-in integrity
Users need a single interface, single standard
Need common vision for the future
