摘　　要：提出一种通过固定广播星历轨道估计精密卫星钟差,实现在一定区域范围内高精度单点定位的方法。基于PANDA软件分析了钟差估计中不同基准站的分布策略,给出我国范围内一组优化的基准站分布策略。实验表明,在此策略下,使用广播星历轨道通过钟差估计能达到静态1 cm、动态6 cm的定位精度。A method for realizing high-precision point positioning in a certain area by fixing the broadcast orbits to estimate precise satellite clock was presented in the paper. Different distribution strategies of reference stations during the clock estimation are analyzed with PANDA and a group of optimal distribution strategies of reference stations in our country is proposed. The experiment results show that the positioning accuracy of 1 cm （static） and 5 cm （dynamic） can be reached using the clock estimation with broadcast orbits with this strategy.
