差分卫星导航系统定位精度飞行测试方法

针对机载差分卫星导航系统的定位误差特性,提出一种考核机载差分卫星导航系统定位精度的飞行测试方法。在事后数据处理过程中,由于两部卫星接收天线之间安装位置不同而导致的杆臂效应会使最终结果产生较大的计算误差,故提出了一种基于消除杆臂的数据处理方法。通过以上飞行测试方法和数据处理方法可以有效地评估机载差分卫星导航系统的定位精度。

Research on Verification Method of Flight Test for Positioning Accuracy of Differential Satellite Navigation System

A flight test method for assessing the positioning accuracy of airborne differential satellite navigation system is proposed,considering positioning error characteristics of airborne differential satellite navigation system. Since the level arm effect caused by the installation location between the two satellite receiving antennas will lead to a large calculation error in the final result in data processing,a data processing method based on lever arm eliminating is put forward. Through the above flight test method and data processing method,the airborne differential satellite navigation system positioning accuracy can be effectively assessed.
