| Abstract: | Conducting GPS positioning,it is necessary to calculate the satellite coordinates at any time.Considering the limitations of the existing interpolation and fitting method,this paper aims at giving a kind of piecewise smooth numerical-approaching method-generalized extended interpolation.This paper discusses the relationship between generalized extended interpolation precision and the choice of three parameters and uses the Chebyshev polynomial to compare and analyze the interpolation results. |
