| Abstract: | In the process of GPS positioning,the accuracy of satellite ephemeris will directly influence the accuracy of ground receiver.The Lagrange interpolation,Neville interpolation and least square fitting method were respectively applied to calculate the GPS satellite ephemeris,and the positioning precision of three algorithms was determined through scientific comparison and analysis.The rational selection of polynomial order and time interval was discussed,which provided the basis for further study of satellite... |
