Due to the satellite-launcher-station interactive operation, coupling of PDOP, reliability and maintainability and supportability (RMS), an availability modeling and simulation method of a navigation system is proposed by GSPN, Bayesian network and outage analysis. The availability of a per-slot is conformed based on GSPN, considering short scheduled or unscheduled outage of bus and payload,long outages, on-orbit or ground backup, testing time in launching site as well as launching reliability. Taking PDOP under different outages as the relationship of slots and the service availability is conformed based on Bayesian network. The vulnerable slots are identified and different optimization designs are compared. The simulation results have demonstrated that this method can be applied for navigation system design optimization, and satellite-launcher-station quantitative decision.
