三种导航卫星故障识别方法的等价性研究

通过分析比较卫星导航系统自主完好性监测算法中常用的三种故障星识别方法,文中提出它们在实质上是一致的观点。从理论上证明这三种方法的等价性,并分别通过模拟数据和GPS观测站的实测数据,验证三者的等价关系。结论对于在不同应用环境下减少识别运算量、提高识别速度有实际意义。

Research on the Equivalence among Three Satellite Fault Identification Algorithms

The current three methods for receiver autonomous integrity monitoring and fault satellite identification of GPS(Global Positioning System)are compared and analyzed.It is concluded that all the three methods are equivalent.The equivalence anong the three methods are proved in principle,and are demonstrated by the stimulant data and observed data from permanent GPS Site.This conclusion is favorable for us to speed up to do the receiver autonomous integrity monitoring and decrease the computation load.
