| 摘 要： | 针对GI-RAIM（GPS Inertial RAIM）惯导辅助GPS接收机自主完好性监测，本文引入了检测时间延迟和检测函数均值偏离度作为评估性能的概念；对比分析了当GPS发生慢变故障（SGE）时，残差检验法和状态多步外推法的故障检测性能。仿真结果表明，状态多步外推法对于慢变故障的检测性能更优越。

| Abstract: | Aimed atGI-RAIM autonomous integrity monitoring, thispaper introduces a concept includingdetecting time delay and average deflection of detecting function as capability ofFD(Fault Detecting), compares Chi-square test with multistep state extrapolationon capabilityof SGE(slowly growing errors) detectingof GPS.At last the simulation result shows that the performance on SGE obtained by using the multistep state extrapolation is better than that by chi- squaretestmethod. |
