| Abstract: | Since the attenuation of the gravitaty field with altitude increasing can be sufficiently compensated by satellite gravity gradiometry,it is possible to recover earth's gravity field with higher precision.On the basis of the satellite orbit perturbation theory,the error of gravity field model from satellite gravity gradiometry mission is analyzed with the time-wise least square method.And the effects of gravity field on the accuracy are presented in maps,due to the choice of SGG parameters(such as satellite's altitude,sampling rates,inclination of satellite and accuracy of gradiometery).The results indicate that time domain least-square method is suitable for the error analysis and the mission design of the measurement of satellite gravity gradiometery. |
| Keywords: | GOCE mission Earth's gravity field satellite gravity gradiometry time domain least squares method error analysis |
