Abstract:

Due to the high requirements of orbit control, satellite-station interactive operation, reliability, and performance assessment, a modeling and analysis method of system effectiveness for a navigation satellite is proposed, considering the outages, random and wearout faults as well as performance. The availability of a navigation satellite is confirmed based on the Markov chain, the reliability is analyzed considering the Weibull and Gaussian distribution, and the performance is normalized by the stress strength interference. The system effectiveness is modeled and analyzed by the factors mentioned above. The medium Earth orbit (MEO) simulation results have demonstrated that this method can be applied for design optimization, and be extended to communications, meteorological, remote sensing satellites.

Key words: Availability, Reliability, Performance, System effectiveness
