“…On 14 December 2013, Chang'E-3 (CE-3), a follow-up to the Chang'E-1 (CE-1) and Chang'E-2 orbiters, successfully landed on Sinus Iridum, the northwest of Mare Imbrium on the lunar near side. It was the first time that China accomplished a soft landing on an extraterrestrial body, and the lunar rover, Yutu, was firstly deployed to operate on the Moon since 1973 [2,3]. Chang'E-4 (CE-4) was originally built as a backup of CE-3, and its configuration was adjusted to meet new scientific and performance objectives after CE-3 succeeded.…”

Chang’E-5 (CE-5) is China’s first lunar sample return mission. This paper focuses on the trajectory determination of the CE-5 lander and ascender during the landing and ascending phases, and the positioning of the CE-5 lander on the Moon. Based on the kinematic statistical orbit determination method using B-spline and polynomial functions, the descent and ascent trajectories of the lander and ascender are determined by using ground-based radiometric ranging, Doppler and interferometry data. The results show that a B-spline function is suitable for a trajectory with complex maneuvers. For a smooth trajectory, B-spline and polynomial functions can reach almost the same solutions. The positioning of the CE-5 lander on the Moon is also investigated here. Using the kinematic statistical positioning method, the landing site of the lander is 43.0590°N, 51.9208°W with an elevation of −2480.26 m, which is less than 200 m different from the LRO (Lunar Reconnaissance Orbiter) image data.
