Orbit Determination and Accuracy Evaluation of Queqiao Relay Satellite for Orbit Maintenance

Abstract

The Queqiao relay satellite which is located in the Halo orbit at Earth-Moon L2 libration point，needs to maintain its configuration by wheel off loading and orbit maintenance every 3-4 days. According to the orbit characteristics of the libration point，the influence of the component of the orbit determination error for the orbit control parameters is analyzed in the rotating coordinate system，and it is concluded that the orbit determination error affecting the orbit maintenance effect mainly concentrate on the velocity error of X-Y plane. In this paper，an orbit determination accuracy evaluation method for orbit maintenance control is proposed，the strategy of orbit determination is designed，and the influence of different strategies on orbit determination is evaluated. The orbit accuracy of the relay satellite in mission orbit is evaluated，and the results show that it can provide 1-3 mm/s velocity accuracy for orbit maintenance under the existing TT&C conditions.

Keywords
