| Abstract: | A GPS receiver autonomous integrity monitoring(RAIM)algorithm aided by the output information of Inertial navigation system is studied in this paper. This method can be used to detect the faults of pseudorange measurement of GPS satellites on the basis of Kalman Filter residual sequence. A computer simulation example is given, the result shows that this algorithm is practical because it can detect the mistaken satellite quickly and accurately. |
