Influence of Tide Perturbation on Autonomous Orbit Determination of Navigation Satellites

We firstly discuss the constellation rotation errors of autonomous orbit determination of navigation satellites,which only make use of crosslink ranging observation.Then,we comprehensively analyze the influence of tide perturbation on right ascension of the ascending node and autonomous orbit determination.The processing results of 110 days' simulation data indicate that tide perturbation has a great impact on the errors of along-track and cross of autonomous orbit determination.Moreover,the impact will become bigger with the increase of days of the autonomous orbit determination.The difference of along-track and cross of autonomous orbit determination on the 110 days because of to tide perturbation is about 4 meters.Therefore,the necessity that consider the influence of tidal perturbation in high-precision autonomous orbit determination is proposed.
