为了确定三视场定位定向设备各个误差源对定位定向误差的影响,建立了定位定向的误差分析模型。首先,给出了三视场导航设备采用空间解析几何法进行定位定向的原理。其次,指出影响定位定向的各个误差源,归纳分析了误差源的特性、概率分布以及误差源对定位定向信息对的影响。然后,利用定位定向原理建立起定位定向误差分析模型。最后,利用蒙特卡罗法进行误差仿真分析。仿真结果表明系统的定位均值误差为121.0 m;定向均值误差为7.4″,并指出定位定向主要的误差源是水平测量误差,其次是垂线偏差数据的误差。野外实验表明,该系统的定位均值误差为182.12 m;定向均值误差为9.3″,水平测倾角的误差对定位定向结果的影响最大。
In order to determine the influence of each error source of the three-field positioning and orientation equipment on the orientation and orientation error, an error analysis model of orientation and orientation was established. First of all, the principle of using spatial analytic geometry to locate and orient three-field navigation equipment is given. Secondly, it points out the error sources that affect the orientation and orientation, and summarizes the characteristics of the error sources, the probability distribution and the impact of error sources on the orientation information pairs. Then, the orientation and orientation principle is used to establish the orientation error analysis model. Finally, using Monte Carlo method for error simulation analysis. The simulation results show that the mean error of the system is 121.0 m and the average error of the orientation is 7.4 “, and the main error sources of orientation and orientation are the error of horizontal measurement and the error of vertical deviation data.The field experiments show that the average of the system location The error is 182.12 m; the error of directional mean is 9.3 ”, and the error of horizontal tilt angle has the greatest influence on the orientation and orientation result.
