A Simulation Study of the Orbit Determination Ability for Chang'E-4 Relay Satellite——Magpie Bridge Under Dual-Station Tracking Mode

Abstract

Limited by the poor observation geometry,a long-term joint tracking data from the ground-based USB/UXB and the astronomical VLBI is required to get the accurate orbit of spacecraft located at the Earth-Moon L2 Libration point. A dual-station tracking mode is proposed to obtain two-way and three-way Ranging and VLBI tracking data to solve the precision orbit. Taking the "Magpie Bridge" satellite as the analysis object,the tracking ability of Chinese deep space network is analyzed first. Then the accuracy of orbit determination with different observation combination is simulated. The results show that under the common-view constraint,the deep-space stations can track Magpie Bridge more than 5 hours per day. To determine the orbit with tracking data longer than 6h,it is better to estimate the systematic bias of ranging data. Once the tracking arc reaches more than 2 days,the solar radiation pressure is expectedto achieve an orbital accuracy better than 100 meters.
