| Abstract: | We to fit IGS precise ephemeris(SP3) with Chebyshev polynomial;The GPS satellite orbital errors are obtained by comparing the interpolated precise GPS satellite coordinates with IGS final orbit.We analyze the errors of broadcast ephemeris in the peak value and trough value of solar activity,are discuss the relationship between the orbital errors of GPS satellite and solar activity according to the space weather. |
