摘要

摘要:
为使接收机自主完好性监测（RAIM）技术应用于民航垂直引导进近（APV）飞行阶段成为可能，研究了BDS/GPS组合导航RAIM算法。提出了一种基于BDS/GPS定位解最优加权平均解的算法，结合最优加权平均解与BDS/GPS定位解的关系建立检验统计量，根据最大允许的虚警率计算检验门限，实现对故障所在卫星导航系统的检测，并采用加权最小二乘残差法对故障进行检测与识别。研究结果对多星座组合卫星导航系统应用于民航APV飞行阶段的导航具有一定的参考意义。

Abstract:
In order to make receiver autonomous integrity monitoring (RAIM) technique be applied to approach with vertical guidance (APV) flight phase in civil aviation navigation, the BDS/GPS combined navigation RAIM algorithm is studied. An algorithm based on the optimal weighted average solution of BDS/GPS position solution is proposed. Combined with the relationship between the optimal weighted average solution and BDS/GPS position solution, a test statistic is established. The test threshold is obtained according to the maximum allowable false alarm probability, and then the satellite navigation system fault is detected. Through the weighted least squares residual method, the satellite fault is detected and identified. The results are instructive for the study of multi-constellation combined satellite navigation system applied to the navigation in civil aviation APV flight phase.
