【摘要】 介绍了测站移动速度对四元素短弧初轨确定的影响.从测站速度矢量的影响因素着手,简化地对移动站的移动速度与影响因素之间的关系进行了理论推导.以单位矢量方法中的3种方法为例,修改了轨道的条件方程,并做了大量的数据验算,最后给出了两圈外测数据的两种不同情况的单圈定轨结果,就此初步分析了移动站的移动速度对定轨结果的影响及规律.这种在定轨方法中补充考虑移动站的移动速度影响的方法,计算模型简洁,容易理解,便于运用.更多还原

【Abstract】 The effects of motion of observation station on orbit determination are analyzed with ranging, angle and velocity data. The relation is given between the velocity of station and its effect on that, and the conditional equations are improved based on unit-vector-method. A lot of calculations have been done and the results show that the improvement is obvious when the motion of observation station is considered.更多还原
