摘要
研究了基线解算时分别使用广播星历、快速星历和精密星历对解算结果的影响。对于长基线来讲,使用快速星历和精密星历可以有效提高解算精度,对于短基线,使用广播星历可以保证基线解算的精度。
This paper studies the effect to the resolving results by using broadcast ephemeris, ultra - rapid ephemeris and precise e- phemeris 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.
