A new method of satellite ephemeris calculation for GLONASS is introduced, which is based on dynamic trajectory recovering. More accurate satellite position can be gotten with no other information but the broadcast ephemeris parameters. The given cases show that all the GLONASS broadcast ephemeris' fitting errors are almost eliminated entirely. The imported error of the propagated perturbation orbit is deducted to several millimeters from 0.5 meter.
