摘要

系统在一定寿命期内正确运行的概率称为可靠性。一个完整的卫星通信系统的可靠性取决于它的两个主要组成部分- -卫星和地面站- -的可靠性。一个完整的卫星通信系统的可用性不仅取决于该系统各组成部分的可靠性，而且还取决于成功发射的可能性、更换时间以及(在轨和地面)运行卫星和备用卫星的数量。地面站的可用性不仅取决于它们的可靠性，还取决于它们的可维护性。对于卫星来说，可用性只取决于可靠性，因为目前的技术无法设想维修。

Measurement of reliability and availability of satellite communication links: Progress and challenges

The probability of correct operation of the system during a given lifetime is called the reliability. The reliability of a complete satellite communications system depends on the reliability of its two principal constituents - the satellite and the ground stations. The availability of a complete satellite communications system depends not only on the reliability of the constituents of the system but also on the probability of successful launching, the replacement time and the number of operational and back-up satellites (in orbit and on the ground). Availability of the ground stations depends not only on their reliability but also on their maintainability. For the satellite, availability depends only on reliability since maintenance is not envisaged with current techniques.
