摘要
Abstract
GPS clock error is calculated, precise ephemeris can be derived from interpola- tion. The main content of this thesis is to provide the IGS precise ephemeris interpolated 15 rain into the 5 min, whichwere used Lagrange polynomials, Chebyshev polynomial to be in- terpolated, and according to the selected interpolating polynomial to a comparative analysis of different order of interpolation accuracy. Details of the Lagrange polynomials, Chebyshev polynomial interpolation of the basic principles and their application are introduced. The ac- curacy of Lagrange polynomials can satisfy the precision requirement for GPS precise positio- ning, and the accuracy of the Chebyshev interpolation is higher .关键词
