摘要
利用广义延拓插值法对GPS精密星历进行插值,探讨插值精度与3个参数的关系,并与Lagrange多项式插值和切比雪夫多项式插值结果进行比较。结果表明,广义延拓插值法具有较高的精度。
The generalized extension interpolation is used to interpolate the IGS precise ephemeris, and the interpolation accuracy and its relation with the three parameters are dicussed. The technique is compared with Lagrange polynomial interpolation and Chebyshev polynomial fitting. The results indicate that the generalized extension interpolation method is with higher accuracy.
