Abstract

Each of the six COSMIC satellites carries one GPS receiver with two antennas for orbit determination (OD) and another two antennas for radio occultation. In this paper we describe the features of the GPS data associated with COSMIC satellite attitude. Method and results of the precise orbit determination for the COSMIC satellites using the tracking data from both OD GPS antennas are presented. Special issues in satellite orbit determination with multiple GPS antennas are discussed. Orbit precision is evaluated and the effects of multipath errors are investigated.
