Abstract：A method for determining precise orbit and clock offset of navigation satellites using zerodifference observation was presented in the paper. Experimental results based on real GPS observation show that when oneday observation of 30 stations all over the world is used, the precision of radial,tangential and normal direction is 0.032 m, 0.084 m, and 0.078 m respectively,and clock offset is 0.18 ns. By comparison of the doubledifference method, the method is easier to operate, and the condition needed is more simple(just one step). So the mthod has better application prospect in the navigation satellite precise orbit determination.
