J. Wolfrum, M. Healy, J.P. Provenzano, T. Sassorossi

Abstract:	The paper covers the various issues that have been ana-lyzed with respect to Europe’s satellite-based global navi-gation system. It outlines preferred solutions and in par-ticular the following issues are addressed: · Technical trade-offs on orbit constellation, transmis-sion frequencies and signal structure · Integrity concept · Ground segment concept including time synchroni-zation and orbit determination · Preliminary payload and satellite design · Transition form EGNOS · Compatibility with GPS The presently selected baselines for Galileo consists either of a MEO constellation of 24 satellites complemented by 3 to 9 GEO-satellites or of a purely MEO constellation of 30 satellites. A global ground segment will guarantee the required integrity.
