Astronautically Phased Mission System (APMS) has the characteristics of sophisticated system structure, complex mission profile and varied system working modes and states. For these characteristics, this paper analyses the mission profile and reliability features (sequential, correlate and dynamic) of APMS, and proposes a method of reliability synthetic modeling considering multi-feature for APMS...
This paper proposes a new method for Astronautically Phased Mission System (APMS) reliability assessment based on Multi-source data fusion. Traditional methods for APMS reliability assessment have two problems. One is lack of overall consideration of the different product hierarchies, different development stages, and different stress conditions data. The other is too difficult to give the reliability...
The power subsystem is one of the most important subsystems of a satellite. This subsystem, supplies the power for the satellite platform and payloads, and ensures the smooth completion of the satellite mission. An accurate reliability assessment and life prediction results provide useful information to for satellite development. This paper takes chooses a sample earth observation satellite's power...
The attitude control system (ACS) is crucial for the satellite operation in the space, and it is a typical phased-mission system (PMS). Some features caused by the system designs bring difficulties in the ACS mission risk analysis, and the traditional risk analysis method probabilistic risk assessment (PRA) must be modified to mo del and analyze the redundant and dynamic features in the system. This...
