摘要
针对“远望”号航天远洋测量船对航天飞行器动态测量的特点,分析了影响船载外测设备测速数据的各种因素,提出了对测速数据进行误差修正的设想和思路并给出了误差修正公式;同时用实战任务中的实测数据进行计算,考察了此方法误差修正的效果。计算结果表明,使用经各种误差修正后的测速数据参与初轨计算能有效提高定轨精度。
According to the characteristics of Yuanwang TT＆C ship＇s dynamic tracking on spacecrafts, this paper analyzes all kinds of elements that may affect velocity measuring data of ship - borne exterior trajectory measurement equipment. It puts forward the idea of performing error correction of the data, presents corresponding formula and also makes some checking computations by taking realtime measuring data in certain spacecraft launching missions as examples. The result shows that using velocity measuring data after error correction in preliminary orbiting computation can effectively improve the orbit determination precision.
