| 摘 要： | 由于卫星的不可维修性和空间环境严酷性的影响,星座中卫星在运行期间可能发生故障,对星座的可靠性造成影响。为此,在星座设计中普遍采用备份卫星策略来解决这一问题。分析了星座卫星备份策略,应用冷储备系统可靠性计算方法,得出了备份策略置信度与卫星备份数量之间的定量关系。

| Abstract: | Because of the rigorous space environment and the non-maintainability of the satellites, the satellites in the constellation may fail during their operation period, and this affects the reliability of the constellation. Spare satellite strategy is adopted in constellation design to deal with the problem. The paper analyses the spare satellite strategies, adopts the algorithm of non-active redundancy system to get the quantitative relation between the number of spare satellites and the certain confidence. |
