Abstract :
A precise relative positioning system using GPS, called PRESTAR, has been developed and is designed to give accurate relative position measurements, precise time synchronization, and precise orbit determinations. PRESTAR uses a high-gain beam antenna to obtain highly accurate range data through the high signal-to-noise (S/N) ratio of the received signal. It makes use of a beam antenna, necessitating a single channel sequential system. Its performance gives accurate relative position measurements, precise time synchronization, and precise orbit determinations have been demonstrated with a 55-km baseline experiment. Longer baseline positioning experiments and orbit determination experiments are being planned. The authors outline the PRESTAR system and some results of experiments
