摘　　要：针对航天测量船外弹道测控系统中影响测控精度的误差源众多、作用机理复杂、测量船现有方法难以从数据残差中自动辨识误差的难题,在给出外测数据轴系参数误差传递模型的基础上,提出了基于误差传递基函数开展匹配追踪的测量船误差溯源方法,通过误差的迭代辨识,匹配误差,定位误差,并准确估计误差值,实现测量船误差的自动识别,提高船载设备误差辨识的效率和精度。仿真分析结果证实了该方法的正确性和有效性。A number of problems influence the accuracy of the data measured by exterior ballistic measure-ment system of space TT&C ship,such as various types of error sources,complicated mechanism of action, and existing ways can't tell the inaccuracy of the residual errors automatically. In order to solve above problems,the error propagating model of the tracking data of axis-systematic is given, and a method for tracing the errors of TT&C ship based on the error propagating function is presented. By iterative identifi-cation,the errors are matched,located and estimated. In this way,the errors of the TT&C ship can be iden-tified automatically and the efficiency and accuracy of ship-borne equipment have been improved. The simulation analysis result also proves the correctness and effectiveness of the method.
