摘要
During regional gravity survey, accuracy of orthometric height may affect the accuracy of gravity survey directly. The field test in Qinghai-Tibetan Plateau show that the accuracy of CQG2000 quasi-geoid model can satisfy the accuracy of orthometric height during the 1∶200 000 regional gravity survey. Based on the test, the authors summarize the method how the accuracy of height measurement can be improved by GPS with CQG2000 quasi-geoid model during the regional gravity survey, which may be helpful to regional gravity survey.
