Abstract:	EGNOS is the European overlay system to the GPS (L1 signals) and GLONASS constellations. EGNOS AOC (Advanced Operational Capability) is currently under its implementation phase, and planned to be delivered to European Space Agency at the end of 2003. GALILEO is the future European GNSS system. In the frame of the INTEG study, led by ALCATEL for the European Commission, a transition scheme for the integration of EGNOS into GALILEO has been defined. This paper presents the high level objectives which have been followed within INTEG study for the elaboration of this transition scheme. Then , it synthesizes the trade-off which have led to the selected architectural approach (the EGNOS+ scenario). Finally, it proposes an approach for implementing this transition, which has been driven by the challenging objective of ensuring a transition without any interruption of the EGNOS AOC services. This paper reflects only the results of the INTEG study: these results have then to be consolidated, together with other studies outputs, by the European Commission for the elaboration of the GALILEO program plan, and therefore, this paper does not necessarily reflect the official position of the European Commission.
