Abstract A method for realizing highprecision 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.
