| Abstract: | When the GPS CV (common view) technique is used for the high-precision time comparisons, the effects of the error of the satellite orbit and the ionospheric delay of the received signal are not negligible and have to be IGS precise ephemeris and CODE global total electron content maps in the GPS time transfers, and it is shown that by using these IGS products the accuracies of the single-station time determination and long-distance time transfer can be effectively improved. |
