Contrast Analysis Between Chi-square Test and State Extrapolation on GI-RAIM
Huang Zhigang · Avionics Technology · 2008
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.
