摘　　要：针对无线电导航系统动态飞行检验时,使用星站差分GPS定位技术存在安全隐患的问题,设计并开展了基于北斗动动实时相对定位精度实验。采用waypoint软件进行差分数据处理,从航向角、俯仰角和基线长度三个方面分析评价短基线和中长基线实时动动差分效果。结果表明:基线精度在分米级别,航向角精度在0.2°以内,俯仰角精度在0.4°以内,北斗动动实时定位数据可作为动对动试验场景下的基准数据。At the hidden trouble of satellite station differential GPS positioning technology in the dynamic flight inspection of Fresnel lens optical landing aid system,a real-time relative positioning accuracy experiment based on Beidou movement is designed and carried out.Waypoint software is used for post difference data processing,and the post dynamic difference processing results are used as standard data to analyze and evaluate the real-time dynamic difference results of short baseline and medium long baseline from three aspects of heading angle,pitch angle and baseline length.The results show that the baseline accuracy is at the decimeter level,the heading angle accuracy is within 0.2°and the pitch angle accuracy is within 0.4°.It can be used as the comparison standard data in the dynamic to dynamic test scenario.
