测角观测误差在初轨确定中的传布

本文用非线性规划方法探讨了初轨确定问题。测角观测误差看作为参数的微摄动，而非线性规划的灵敏性分析模型（ｆｈｐ） 建立在无摄动的情况下。由此，得出了在一阶近似下轨道根数计算值和测角观测误差值间关系的分析表达式。

A NOTE ON THE PROPAGATION OF ANGLE ONLY DATA ERROR IN INITIAL ORBIT DETERMINATION

In this paper, the problem of initial orbit determination is discussed with nonlinear programming method. The angle only data error is treated as mini disturbance of parameters and the sensitivity analysis model ( fhp) on nonlinear programming is established in the case without disturbance. From this, an analytical formula is deduced to express the relationship between the calculated value of the orbit element sets and the angles only data error (on the first order approximaiton).
