| 摘 要： | 由地心运动引起的引力位1次项系数不为零会对卫星轨道产生摄动。文中主要通过模拟计算来研究地心运动或坐标系统不自洽引起的地心偏离，从而对不同轨道根数的卫星轨道产生的摄动量级。实验表明地心运动对卫星轨道的影响，在高精度精密定轨和反演地球重力场中也是需要顾及的一项内容，特别是在坐标系统不自洽的情况下，影响更大。

| Abstract: | The Motion of the Earth's Center of Masses will make 1th coefficient of the gravitational potential of the earth unequal to zero, and it will bring perturbation of satellite orbit. This paper studies the effect of satellite orbit by the motion of the earth's center of masses and the disagreement of coordinates system. The experiment expresses that the effect of the motion of the earth's center of masses should be corrected in the exact determination of satellite orbit and the inversion of earth's gravity field. |
