| 摘 要： | 卫星导航接收机自主完好性监测RAIM是利用接收机自身的冗余观测值进行卫星故障的检测和识别,根据现有RAIM算法进行故障检测,有较大的漏警率。该文通过研究基于最小二乘残差的故障检测和识别方法,提出了一种改进的RAIM算法,有效地降低了漏警率。该算法在某型号接收机的相关实验中取得了较好的效果。

| Abstract: | The receiver autonomous integrity monitoring (RAEM) uses the redundant measurements to detect and exclude fault. The probability of missed detection is high when using the current RAIM algorithm in fault detection. An improved RAIM algorithm which can reduce the probability of missed detection is presented in this paper. The approach of fault detection and identification based on least squares residuals method is studied. The experimental results in a certain type of receiver indicate that this algorithm is effective. |
