介绍了几种现有的以GPS/北斗为主要代表的卫星导航系统的动态定位精度鉴定方法,分析了这几种方法在模拟实际使用环境、鉴定精度等方面的优缺点,提出了一种基于火箭橇试验平台的北斗导航定位系统动态定位精度鉴定方法。该方法能够很好地模拟北斗导航定位系统实际工作环境(速度、加速度、振动和天线角度等),解决高动态、高精度北斗导航定位系统动态定位精度鉴定问题,并对该方法的原理和实施方法作了详细的论述,最后分析了该方法的不确定度及误差,并提出了改进措施。
This paper introduces several existing identification methods of dynamic positioning accuracy of GPS / GPS satellite navigation system, and analyzes the advantages and disadvantages of these methods in the simulation of actual use environment, identification accuracy and so on. Identification Method of Dynamic Positioning Accuracy of Beidou Navigation Positioning System for Rocket Sled Experiment Platform. The method can well simulate the actual working environment (velocity, acceleration, vibration and antenna angle) of Beidou Navigation and Positioning System and solve the problem of dynamic positioning accuracy of Beidou Navigation and Positioning System with high dynamic and high precision. The principle and implementation of this method Methods are discussed in detail, and finally the uncertainty and error of the method are analyzed, and the improvement measures are put forward.
