An Integrated Relative Navigation System Using GPS/VISNAV for Ultra-close Spacecraft Formation Flying
To improve the accuracy and better fault-tolerant performance for ultra-close spacecraft formation flying, a Global Position System (GPS)/Vision based Navigation (VISNAV) integrated Relative Navigation and Attitude Determination (RNAD) approach was presented in this paper. Onboard GPS was used for RNAD for formation spacecraft by multiantennas configuration. The same RNAD information was also achieved by VISNAV system separately by using multiple line-of-sight vectors observations from spacecraft to another. Optimal fusion of RNAD information from both GPS/VISNAV subsystems was achieved by a Federal Kalman Filter (FKF) architecture. Simulation results provided later indicate that the integrated system can provide a total improvement of relative navigation and attitude estimation performance in accuracy and fault-tolerant.
