Abstract
For characteristics of satellite-ground operation, complex relationship, reliability, maintainability, and supportability, Petri net (PN) and Bayesian network (BN) are applied integrated to dependability modeling and analysis of precise orbit determination in this paper. The hardware fault, software fault, and coupling fault are considered for availability of monitor stations based on PN, and the state transition of a monitor station can be obtained. The orbit determination algorithm, outage analysis, stress intensity algorithm are taken into account for dependability of precise orbit determination based on BN, and the transition of performance and reliability can be researched. The weakness of monitor stations is confirmed and improved schemes are given. The regional monitoring network results show, this method can be used for dependability analysis and design improved, and extended to upload mission, integrity monitoring mission, and so on.
