摘要: 介绍了滑动式广义延拓逼近法的原理,然后利用这一算法,分别探讨了不同单元域节点数、逼近函数项数、延拓域节点数组合与三类不同北斗卫星插值精度的关系.实际算例表明,三类北斗卫星达到最佳插值精度的三参数取值不同;只要选取合适的三个参数,三类不同北斗卫星的插值精度都可以达到很高的精度.该方法完全适用于北斗卫星精密星历的插值.

Abstract: The principle of sliding generalized extended approximation method is introduced. Based on this algorithm,the relationship among different combinations of the number of nodes in unit domains, the number of approximation functions,the number of nodes in extension domain and the interpolation accuracy of three different BeiDou satellites is respectively discussed. The actual example shows that the three parameters of the three kinds of BeiDou satellites to achieve the best interpolation accuracy are different;as long as the appropriate three parameters are selected,the interpolation accuracy of the three different BeiDou satellites can reach a very high accuracy.This method is completely applicable to BeiDou satellites precise ephemeris interpolation. -
