Abstract :
This paper firstly analyzes the concept of availability of satellite constellation. Then the method of constellation availability analysis is proposed on the basis of Markov chain model, outage analysis, as well as MTBF and MTTR of satellite constellations. Finally, an illustrative example is presented to validate the method.
