用卫星两个时刻速度向量计算初轨的方法

Determination of the Initial Satellite Orbit by Using Two

本文介绍了仅用卫星两个时刻速度向量计算卫星初轨的方法。不需要知道卫星的位置和其它观测值。计算结果均可以做为轨道改进和计算星历时的人卫初轨近似值。对所提的方法进行了详细的论述。

This paper introduces methods of calculation the initial orbit of the satellite only with the velocity vectors of two epochs. The position of the satellite and other measearements are not needed in the methods. The results can be used as approximate values of the initial satellite orbit to correct the orbit by integration or calculate satellite ephemerides. The method is discussed in detail.
