基于火箭橇的北斗动态定位精度鉴定方法

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。

A Method of Dynamic Position Accuracy Evaluation for BeiDou Based on Rocket Sled Test

In this paper some methods of dynamic position accuracy evaluation for satellite navigation system represented mainly with GPS/BeiDou are presented. Then we analyze advantages and disadvantages of the methods in simulating about working environment and accuracy assessment. A new method of dynamic position accuracy evaluation for BeiDou based on rocket sled test is proposed. The method can simulate working environment well of BeiDou navigation positioning system, such as velocity, acceleration, oscillation, antenna angle. The dynamic position accuracy evaluation for BeiDou navigation system in accuracy evaluation of high-dynamic and high accuracy is solved. This paper detailedly dissertates theory and implementation approach of the method. Then an analysis of uncertainty and error for the method is presented. Finally, improving measures are proposed.
