Abstract：Navigation Constellation may drift in secular operation because it lacks the inertial benchmark only based on the measurements of intersatellites links.Firstly，the technique of groundbased anchomethod is used to deal with the observability of the constellation in theory.Then，AREFK(AugmentR Extended Kalman Filter）algorithm is used to settle the problem of the distributed autonomous orbit determination of the navigation constellation and validated the simulation lastly.The simulation results indicate the autonomous orbit determination can satisfy the needs of accuracy of the navigation and position.
