基于在轨运行状态的卫星稳定性与可靠性研究

摘要

为解决卫星在轨运行故障率较高的问题，文章分析了卫星在轨运行的特点，定义了卫星在轨工作状态及其与系统稳定性变化的关系。研究表明：对在轨运行安全稳定状态进行控制，能使状态保持或向高级跃迁，可提升卫星稳态及可靠性。文章最后提出了提高卫星在轨运行稳定性与可靠性的在轨运行策略与技术方向。%To solve the problem of the high fault rate of in-orbit operation of satellite, the characteristics of in-orbit operation of satellite are analyzed. The in-orbit operational status of satellite is defined and is correlated with the stabilization of satellite in orbit. Furthermore, the in-orbit fault recognition and diagnosis, the fault strategies, the operational mechanism and procedures for in-orbit management, and the reliability engineering requirements and the technological direction for in-orbit operations are discussed. It is shown that the status transition can be achieved to promote a steady state and the reliability by controlling the operational safe and stable state of satellite in orbit. The article finally proposed the strategy and technology direction to improve the stability and reliability of satellite in orbit.
