摘要
以惯性导航系统输出的数据作为辅助信息 ,对 GPS完善性监测算法进行了研究。该法以卡尔曼滤波新息序列为依据 ,对 GPS卫星的伪距测量值是否出现故障进行的检测 ,并给出了计算机仿真算例。仿真结果表明 :该方法能够及时准确地检测出
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.
