GPS卫星摄动力数值分析

Numerical Analysis of Perturbation Forces of GPS Satellites

  • 摘要: 先由IGS精密星历计算出GPS卫星的总加速度,此加速度可以作为卫星在空中飞行时所受全部力作用的结果;利用现有的力模型计算了部分摄动力对卫星产生的加速度,对这两种方法所得加速度进行了比较。结果表明,现有的力学模型与卫星运动中所受的实际作用力之间仍有不可忽视的差距。

     

    Abstract: Using the IGS precise ephemeris,the acceleration of GPS satellites can be computed,which can be regarded as the result of all forces.Based on mechanical models,all kinds of perturbation accelerations can be computed.The accelerations of two methods are compared and analyzed.It's concluded that the difference between mechanical models and true forces of satellite is evident.
