摘要
以GRACE卫星计划为范例,通过数值方法建立SST观测量与地球引力位的关系式,为后续反演地球重力场数值算法的实现建立基础。
The satellite-to-satellite tracking observations include light-of-sight-distance, light- of-sight-velocity and light-of-sight-acceleration, which reflect the various-band information of the Earth gravity field. To extract these information, the relationship between the SST observations and the Earth gravity field coefficients should be establishend. Three types of ob- servation equations are created. And these equation could be realized with numerical method conveniently.
