In-Orbit Verification for Accelerometers Using Rotating Spacecraft Method

利用旋转卫星法开展高精度空间加速度计在轨性能检验的可行性分析表明该方法能够在轨测量加速度计的分辨率、质心重合度、标度因数和安装误差,并根据GRACE卫星的相关参数估计了采用该方法可能达到的测量水平,这不仅有利于加速度计载荷在轨性能评价,而且对于重力场测量卫星的最终数据处理具有指导意义。

A feasibility analysis of in-orbit performance verification of a high accuracy accelerometer by rotating spacecraft shows that resolution,center of mass offset,scale factor and misalignment of the accelerometer could be measured,and the expected measurement accuracy using this method based on the parameters of the GRACE mission is also presented.It is not only helpful to verify in-orbit performance of the accelerometer,but also significant for the data processing of gravity field determination from satellite.
