GPS orientation need calculate GPS satellite position information which can ascertain user position. In order to orient fleetly and veraciously, user must get GPS satellite position exactly. The paper analyses the GPS broadcast ephemeris, and presented a new method which calculate GPS satellite position utilizing the GPS broadcast ephemeris and iterative technique. The way has fast calculation speed and high nicety.
