摘要
大地水准面重力位的系统误差或重力位漂移δW会直接影响地球外部重力场以及高程基准。传统的确定δW的方法比较复杂,不易实施。简述了虚拟压缩恢复法,并基于该法给出了漂移方程,用以确定大地水准面重力位δW。初步的模拟实验结果证实了漂移方程的可靠性和有效性。
The geopotential system error or the geopotential shift δW exerts direct influences on the gravity field as well as the datum height system. Conventional approach for determining the shift δW is complicated and difficult to be realized. This paper introduces the fictitious compress recovery approach and a shift equation based on which is given. Preliminary experimental tests show that the shift equation is valid and reliable.
