Influence of the Satellite Motion on Satellite-Borne Acceleration Sensor

  • 摘要: 加速度传感器测量卫星所受非引力加速度的精度是利用该技术精确恢复重力场的重要指标。根据卫星运动理论,给出了轨道升交点赤经摄动、近升距摄动、卫星运动、坐标轴旋转引起的加速度性质以及相应表达式。针对CHAMP卫星轨道,讨论了各项的影响量级。

     

    Abstract: On the basis of the satellite perturbation theory and vector operation principle,the acceleration characteristics and its expression are presented.As to CHAMP's satellite orbit parameters,the magnitude orders of every perturbation item are computed.The results show that the acceleration correction magnitudes produced by the perturbations of the right ascension of the ascending node and the argument of perigee and by the indirect perturbations of the satellite motion and the coordination rotation are below 10-11 m·s-2 which can be neglected.
