| Abstract: | This paper studies the effect to the resolving results by using broadcast ephemeris,ultra-rapid ephemeris and precise ephemeris respectively in the baseline solution.It is effective to improve the accuracy in resolving using precise ephemeris and ultra-rapid ephemeris for the long range baseline.And it can guarantee the accuracy in resolving using broadcast ephemeris for the short range baseline. |
