SATELLITE TO SATELLITE RELATIVE NAVIGATION USING GPS SIGNAL SIMULATORS

P. W. Binning - Naval Research Laboratory

Abstract

The Naval Research Laboratory's orbit determination software OCEAN processes GPS pseudoranges for relative satellite to satellite navigation. A number of algorithms are developed which are used to quantify relative position errors. The software consists of an extended Kalman filter and a backwards discrete smoother. A Northern Telecom GPS signal simulator and an Allan Osborne Associates TurboRogue receiver are used to simulate a number of relative orbit conditions.
