Research and simulation of distribution of intersection measurement points with multiple photoelectric theodolites’
【摘要】 针对多台光电经纬仪交会测量时的布站问题.根据误差传递公式得到基本布站方式;采用最小二乘法对观测方程进行处理,并获得其空间坐标误差的计算公式,再进行误差仿真,从而确定最优的布站方案.结果表明,当目标位于观测站正前方范围内时,合理布站可显著提高光电经纬仪对空间飞行器坐标的测量精度,对机动大目标的坐标测量误差小于0.20m.
【Abstract】 This paper mainly discussed the distribution of intersection measurement points with multiple many photoelectric theodolites.First,primary distribution of measurement points are derived according to formula of error transfer.Second,calculation formula of spacial coordinate error is educed,processing measurement function by least square algorithm.The optimum distribution is determined be measurement error simulation.The results show that reasonable distribution of measurement points can improve the measurement accuracy of coordinate obviously and for the mobile large target its coordinate measurement errors are less than 0.20 m while target is located in front of measurement point.
