摘要: 将卫星地面跟踪、高低卫星跟踪和低低卫星跟踪恢复重力场的原理进行统一,导出了两种能充分综合多种跟踪观测的卫星重力场恢复基本观测方程。在建立基本观测量与重力场参数的函数传输关系的基础上,对目前存在的重力场恢复算法给出了直观的解释,并以距离二次变率为重力场恢复的基本观测量,提出了一种能组合各种卫星跟踪观测量的动态/动力组合定轨和重力场恢复方法。Abstract: Two basic observation equations for gravity field recovery are presented.The existing algorithms are classified on the angles of expression mode of transfer coefficients matrix from gravity field parameters to basic observations.A data processing method about kinematic/dynamic orbit determination and gravity field recovery is introduced.
