| 摘 要： | 对星载加速仪进行校标是有效利用星载加速仪测量数据的基础,目前校标方法都是建立在星载GPS资料处理的基础上,对处理软件和计算设备的要求都非常高.为了满足高层大气阻力研究的需要,提出了一种快速高效的校标方法,即利用GFZ公布的CHAMP卫星快速轨道作为观测资料,采用有尺度因子和线性偏差的加速仪测量值代替非引力模型摄动加速度...

| Abstract: | A rapid and effective calibration method for CHAMP accelerometer is developed in this work,the rapid CHAMP orbits published by GFZ are used as observations,the in-orbit calibrated accelerometer observations are used to replace the non-gravitation,and the calibration parameters,include scales and biases in the xyz direction of instrument fixed system,are estimated in the process of precise orbit determination,and in the meantime of 6 initial orbit elements estimation. To improve the reliability of calibratio... |
