完好性是卫星导航系统的核心性能指标之一，卫星自主完好性监测是地面运控工作模式下导航系统完好性监测的重要补充。围绕卫星导航信号观测量的完好性监测问题，给出伪距及载波观测值、伪码载波一致性以及多路伪码相位一致性指标的完好性监测方法，以及检测量的设计，并通过仿真计算得到满足民航信号空间完备性设计要求的检测门限和最小可检测异常值，为卫星导航自主完好性监测终端的设计提供了理论参考。

Integrity is one of the most key factors of satellite navigation system. Moreover, satellite autonomous integrity is an important part of operational controlling and monitoring the global navigation satellite system(GNSS). This monitoring of the satellite autonomous integrity monitoring(SAIM) observations was concentrated on, including the specific monitoring methods and detection tests of pseudo-range, carrier phase, carrier-code coherence and multichannel code phase coherence. According to the civil aviation integrity regulations, the detection threshold and the minimum detectable abnormity were calculated, which provided some theoretical reference for terminal design of SAIM.
