Abstract:

For the improvement of accuracy and better faulttolerant
performance, a global position system (GPS)/vision navigation
(VISNAV) integrated relative navigation and attitude determination
approach is presented for ultra-close spacecraft formation
flying. Onboard GPS and VISNAV system are adopted and
a federal Kalman filter architecture is used for the total navigation
system design. Simulation results indicate that the integrated
system can provide a total improvement of relative navigation and
attitude estimation performance in accuracy and fault-tolerance.
