Abstract

Abstract: Determination of the relative states is the primary and important guarantee for normal operation of microsatellite formation. With the miniaturization and lowcost spaceborne GPS receiver, the accuracy of orbit determination is low. In order to solve this problem, a method of correcting the formation relative orbit is given with only intersatellite ranging information used. Intersatellite ranging information is introduced and the extended Kalman filter is used to enhance the estimation accuracy of the relative orbit. The numerical simulation results show the validity of this approach.

Key words: ：microsatellite formation, GPS, Intersatellite ranging, relative state determination, extended Kalman filter
