摘要
推导了高椭率地球轨道卫星时钟的原时改正公式。在考虑地球扁率以项摄动的情况下，给出了卫星原时到地心坐标时（geocentric coordinatetime，TCG）的时间改正分析解。通过与数值解的对比，给出了该分析解的精度。结果显示，分析解的精度周期项振幅可以达到0．15ns／d，长期项约为0．06ns／d。
In this paper, an analysis solution of proper time transformation of the satellite is introduced. The Earth＇s oblateness J2 term is included in the transformation equation. The analysis result is compared with the numerical result. And the comparison shows that the periodic difference between them is smaller than 0.15 ns/d, and the long term difference is 0.06 ns/d.
