摘要：
For the orbit of Chang'E-4 lander around the Moon, the precision orbit determination and accuracy analysis is performed based upon Doppler measurements. The algorithm for high precision Doppler modeling is proposed. The Doppler measurements of Chang'E-4 during lunar flight phase are processed in this paper, including the following three aspects: the influence of attitude control, orbital overlap and comparison with independent orbit. The results show that the reaction jet attitude control can accelerate the spacecraft slightly and affect the orbital calculation by 20~50 m. By overlap comparison, the accuracy of independent orbit calculation with Doppler data during the stable flight phase is better than 30 m. Compared with the joint orbital calculation with ranging and VLBI measurements, the orbital difference is less than 50 m. © 2020, Editorial Dept. of JA. All right reserved.
