| Abstract: | On the basis of analysis about Inertial Surveying System errors and anomaly gavity field efflection, two kinds of models which used to estimate gravity anomaly and vertical deflection are presented here. From the analysis to the simulated computation results reliability of the models and applicability of the results are indicated. In addition, the influence of some system errors to anomaly gravity and vertical deflection estimation accuration is explained, and finally some problems on Kalman Filterring application are discussed. |
