卫星重力测量中加速度计在轨参数校准方法研究

In-orbit Calibration Methods of Accelerometer Parameters on Satellite-borne Gravimetry

文章介绍了静电悬浮加速度计的基本工作原理,概述了目前卫星重力测量中加速度计参数的在轨外部校准方法,讨论了利用推进器推力、卫星旋转产生的离心力、引力开展加速度计标度因数在轨实时标定的可行性。

The operation principle of the electrostatic space accelerometer was introduced, and the calibration methods of the accelerometer parameters in-orbit for the present Earth＇s gravity field survey missions were outlined. The feasibilities of the methods which are executed by the means of the thrust forces, the centrifugal forces due to the satellite rotation motions, and the gravitation forces, to determine the scale factor of the accelerometer in-orbit, were analyzed.
