提出并实现了一种求解静地轨道GEO(geostationary orbit)卫星Hill方程摄动解的分析型方法。根据地固坐标系下GEO卫星运动的特点,在其定点处把摄动力进行泰勒展开,通过选择特定的参考轨道获得了GEO卫星的地球扁率摄动解。在此基础上,成功地将拉普拉斯变换运用于GEO卫星的Hill方程,得到了一组可用于求解摄动分析解的递推积分公式。通过逐次趋近的方法,利用这组积分公式可以有效地实现由低阶解推求高阶解。
A new analytical method for solving the GEO (geostationary orbit) satellite hill equations was developed in this paper. In terms of the GEO satellite' s motion trait, the perturbing force was expanded in the form of Taylor series at the geostationary point. Then an analytical solution which contained the flattening perturbation of the earth was obtained by choosing a special reference orbit. Based on the obtaining analytical solution, the Laplace transformation was applied to the GEO satellite Hill equations, and a group of integral formulas used to develop the analytical perturbing solution order by order was obtained.
