Abstract:	Different navigation systems ( ground and on board equipment ) have been studied in order to design an autonomous navigator for a geostationary satellite. This study focuses on the hardware system description, the mission analysis and the orbit determination accuracy obtained with the presented kinds of localisation measurements. The presented comparison study considers different navigation techniques based on C/A code characteristics with a dedicated CIA code on board receiver : a) The use of the C/A codes transmitted by the GPS satellites ; b) Transmission in Ku, C or S-band of C/A codes by 3 dedicated ground pseudolites, or by feeder-link stations of the host satellite ( in Ku-band ). This paper presents the characteristics of each radionavigation system ( theoretical background, kind of measurement, frequencies, error models ) and the method used to estimate the orbit determination accuracy. Then, the results are compared and discussed. System specification of the on board receiver are given in each case. The use of the studied system on board geostationary radionavigation satellites is also discussed. Some studies concerning GPS navigation for geostationary transfer orbits are also described. The GPS application planned for the STENTOR program is also presented.
