中文摘要：
探讨基于相关分析理论的组合导航RIAM方法，并给出单个和多个探测粗差的相关分析检验流程。通过模拟12颗GPS和Galileo组合导航卫星定位系统，分别给单颗和两颗正常卫星加入粗差。仿真结果表明：观测值的影响向量与残差的相关系数可以定位含粗差的卫星并将粗差卫星予以剔除。
英文摘要：
The principle, calculation method of correlation coefficient, and its significance test were described Focusing on integrated navigation RAIM model, the integrated navigation RAIM method based on correlation analysis theory was probed, testing process of single and multiple gross errors detection was presented. By simulating the 12 GPS and Galileo navigation satellite positioning system, outliers were added to single and two satellites, respectively. Simulation results show that the correlation coefficient of observations＇ influence vector and residual error can locate and remove satellites which contain gross errors, improving the navigation positioning accuracy.
