小卫星故障诊断与处理技术

介绍一种简单有效的故障诊断及处理技术，它将小卫星的故障分为分系统级，系统级和系统外部级三种，并由星务管理软件处理系统级故障，在每个循环周期都对遥测参数进行采集和监测，故障发生时，根据故障的优先级，选择并恢复具有最高优先级的故障。该技术在某小卫星中应用，能有效满足系统控制周期的限制和系统可靠性要求。

Fault Detection Isolation and Recovery for the Small Satellite

A simple but effective fault diagnosis and processing technique is introduced. The failures of small satellite are divided into three levels: sub system level, system level and outside system level, and the failures in system level are processed by housekeeping software. The telemetric parameters are sampled and monitored in each control cycle. When failure occurred, only the highest priority failure is selected and recovered. This technique is applied in small satellite, and satisfies the limitation of control cycle and reliability requirement of system.
