Aiming at the problem of the low accuracy of the geomagnetic navigation and the remote sensing image orbit determination is discontinuous, an autonomous orbit determination (AOD) scheme combining remote sensing image with geomagnetic navigation is proposed. The method introduces high-precision remote sensing image position calculation information into continuous geomagnetic/astronomical autonomous orbit determination, and uses RPNP algorithm to perform position resolution of remote sensing image; the filter takes sun sensor, star sensor and magnetometer as the observations, and uses Federated Adaptive Unscented Kalman (FAUKF) to filter. The accuracy of the simulation after stabilization is 174.37 m, which means the proposed scheme has fast convergence, and the improvement of the accuracy of orbit determination is obvious, which can effectively increase the accuracy of geomagnetic autonomous orbit determination.
