摘　　要：由于GPS测量的精度与GPS卫星的分布和观测时间的长短密切相关。本文提出根据预报星历预报的卫星分布情况对GPS控制网的网形和观测方案进行优化;并结合预报星历和观测时间,对GPS控制网基线的精度和权的确定方法进行了探讨。There is a correlation between the precision of GPS survey and GPS satellite distribution. In this paper, based on forecasting ephemeris, the method of optimum design on the form and scheme of GPS network is given. And how to determine the precision and the weight of GPS network baseline is also discussed.
