接收机自主完好性监测技术研究

Research on Receiver Autonomous Integrity Monitoring

对卫星接收机完好性监测技术进行了简单的介绍,以最小二乘法对接收机自主完好性监测(Receiver Autonomous Integrity Monitoring,RAIM)的基本公式进行了详细的推导和分析,以奇偶矢量法在实际工程应用中验证了RAIM算法的正确性和可行性。在此基础上,提出一种新的故障卫星排除算法-均方根(Root Mean Square,RMS)比较法,工程验证了算法的有效性,具有较强工程应用价值。

A simple explanation is put forward based on Receiver autonomous integrity monitoring, the least square method RAIM algorithm is firstly analyzed in detail, identifies and verifies correctly and feasibility about parity RAIM algorithm that apply in realistic project. And then a new receiver autonomous integrity monitoring approach was proposed for detecting and identifying satellites fault - RMS. The new algorithm has a significant improvement in performance of integrity monitoring.
