摘要
本文对长度不同的基线分别使用广播星历和精密星历进行解算,分析了两种星历对基线解算结果的影响。通过对解算结果的比较得到使用广播星历的最佳基线长度范围,结果表明,对于长度小于100 km的短基线而言,广播星历能够达到与精密星历同样的效果。
The length of GPS baselines less than 100 kin were processed through broadcasting ephemeris and precise ephemeris, then the impact were analysized. Based on the two ephemeris, the length scope of the best baseline for broadcasting ephemeris were achieved. If the baseline length less than 100 kin, the results showed that the results are the same when using broadcasting ephemeris and precise ephemeris.
