卫星轨道摄动的小波平滑

Analysis of Orbital Perturbation of Satellite via Wavelet Smoothing

人造卫星的摄动变化规律是一个十分复杂的问题,对其各种因素影响的分析是极其困难的。本文在轨道根数摄动计算的基础上给出了一种基于小波分析的方法,能够对轨道摄动作出很好的精确预测,而且能够消除计算和实际存在的噪声误差,对信号作出很好的平滑。

Orbital perturbation of satellite is a very complicate problem. It抯 hard to analyze all factors. In this paper a new method wavelet smoothness based on the perturbation computing results is presented. The method has a high performance in approximation and prediction. Moreover, it can remove noises of computing results and real world, and it has a good smoothing of the signal.
