Fault Tolerance of Relative Navigation Sensing in Docking Approach of Spacecraft

This paper analyzes fault tolerance of spacecraft relative navigation in automated rendezvous and docking (ARD the parameters are determined by Monte Carlo simulations of the near field docking approach. The integrated Markov Chain model allows the probabilities of mission abort and a mishap to be computed. The results of the trade study include dependence of the probabilities on the backup sensor activation delay.
