一种天基测向初轨确定方法

An Initial Orbit Determination Method Using Space-based Angle Data

研究了测向数据下的天基初步轨道确定,提出了一种矢量投影法,利用矢量投影建立了基本条件方程组,把现有方法统一起来,并易于扩展为其他类型观测数据下的初定轨。同时研究了迭代初值求解、平凡解初值消除与迭代加速方法等相关问题。采用仿真算例检验本文提出的方法,仿真结果证明了本文方法的有效性。

A space-based orbit determinafon method using angle data is discussed in this article, which proposes the method of Vector Projection by uniting several present methods. It is convenient to be extended for other data types, and to build the based condition equations. Meanwhile, the correlative issues are studied, such as evaluation of initial iteration values, elimination of uniform solution and iteration acceleration. The numerical simulations in the end show that the new method is effective and swift in achieving a satisfying result.
