Fault and Detection Performance Definition of Beidou Satellite Space Signal

  • 摘要: 卫星导航系统指标分配与论证是指导和约束各大系统方案设计及工程实现的重要依据.完好性和连续性是系统服务性能的关键指标,能否满足用户需求主要取决于其中的空间信号故障和监测性能指标.以用户完好性和连续性要求为设计依据,定义了空间信号故障次数、平均故障率、故障漏检率、虚警率等系统指标与完好性、连续性等风险概率之间的转换关系.针对北斗系统及星座构成特点,按照国际民航组织规定的用户完好性和连续性风险概率需求,分析了不同空间信号故障条件对系统完好性监测性能的指标要求.研究结果可为北斗全球系统可靠性指标论证和设计提供依据和参考.
