TL;DR: In this paper, the authors present the results on precision orbit determination and positioning of the lander and the rover, and describe the data, modeling, and methods used to achieve position knowledge over the period December 2-21, 2014.

TL;DR: In this article, the authors analyzed the measurement data of the Chang'E-5T spacecraft for a trial in the Chinese lunar exploration program, and the position error in the one-hour prediction from the orbit determination using GNSS single-difference pseudorange in the 1.5h arc was less than 109m, while that from the result using range and Doppler data in the 3h arc is 369m.

TL;DR: In this paper, a kinematic statistical method is proposed to determine the position for Chang'E-3 (CE-3) lunar lander, which uses both ranging and VLBI measurements to the lander for a continuous arc, combing with precise knowledge about the motion of the moon as provided by planetary ephemeris.

TL;DR: In this paper, the authors evaluated the ground tracking data including ranging, Doppler, VLBI delay and rate of the CE-4 relay satellite, and showed that the residual RMS of ranging, doppler and delay rate based on S-band are about 0.53m, 0.37mm/s, 1.16 ns and 0.67 ns, respectively.

TL;DR: Wang et al. as mentioned in this paper presented the orbit determination process and result of Tianwen-1 in the phase of Earth-Mars trajectory in detail, which was carried out based on the tracking data obtained by CDSN (Chinese Deep Space Network) and CVN(Chinese VLBI Network).
