利用数值法获取两行根数

Determination of Two-Line Elements with Numerical Method

  • 摘要: 从应用角度探讨了如何利用数值方法获取两行根数(TLE)。该方法的特点是以差商代替微分,避免了繁琐的偏导数求解。结果表明,该算法简洁明了,运算速度快,适用于要求实时性的应用。

     

    Abstract: SGP4 is an orbit prediction software based on the analytic theory,its input data is two-line elements(TLE) specially defined NORAD.In order to get TLE,a numerical method is discussed,especially on displacing the differential coefficients with numerical differences.The results show that the method is effective.
