Project Galileo, An Overview

Sigfrido Leschiutta, Patrizia Tavella

Abstract:	Some years ago decision was taken by EC - the European Community Commission - to study the feasibility of a global satellite navigation system; the main requirements were to design a full system, complementary but independent from GPS. An additional requirement was the integrity service. The aim of this paper is to present a overview on the activities performed in the years since 1999 and the major issues insofar agreed. For this purpose, four points are covered: - the main lines of the project, as stands at the end of 2001, pointing out similarities and differences with respect to GPS, - the organization of the research effort mounted in 1999-2001 by EC and ESA (European Space Agency), - the relations with EGNOS (European Global Navigation Overlay System), the counterpart of the American WAAS, and finally, - the developments foreseen at the moment. Also the financial envelope will be presented. The aspects related to precise time and timekeeping will be examined, covering the current European projects of clock development, clock synchronization, time scale formation, and the relationship with the UTC community.
