| 摘 要： | 卫星初轨确定在卫星轨道改进中起着重要作用.随着测量技术的发展,测量数据不断增多,为初轨确定提供了良好的基础.常见的方法有多项式逼近,切比雪夫多项式逼近.然而在实际初轨确定过程中,它们存在很大的缺点:主要是逼近精度不高.根据实际测量数据,提出了用样条函数逼近的方法来获取初始轨道,这种方法具有逼近精度高,实际容易操作的优点.并且通过计算结果进行了比较,指出了多项式逼近和切比雪夫多项式逼近存在的不足.

| Abstract: | Initial orbit determination plays an important role in orbit determination.With the development of measurement technology,the data become more and more,which provides a good foundation for initial orbit determi- nation.The general methods are polynomial approximation and Chebyshev approximation.However they have low pre- cision in practice.In this paper a spline function approximation method is presented according to observation data, furthermore the defaults of polynomial approximation and Chebyshev approximation by computation are described. |
