In the early morning of April 23, 2025, Beijing time, China successfully achieved satellite laser ranging at the scale of the Earth-Moon distance (about 350,000 kilometers) for the first time. This new satellite laser ranging technology experiment was carried out by the Chinese Academy of Sciences' "Earth-Moon Space DRO Exploration Research" Class A pilot project through the DRO-A сателитен рефлектор на конуса с едноъгълник и 1 . 2M система за лазерно лазерно лазерно ниво на бленда.
The experiment was organized and implemented by the Space Application Center of the Chinese Academy of Sciences. The Shanghai Astronomical Observatory was responsible for the development of the satellite-borne reflector, the Yunnan Astronomical Observatory was responsible for the development of the ground laser ranging system, and the Microsatellite Innovation Institute was responsible for the development of the satellite platform.
Among them, the satellite-borne reflector adopts a large-aperture single-corner cone design, overcomes the micro-radian level dihedral angle control, low-temperature difference mirror thermal control, and speed difference matching far-field diffraction design technology, and maximizes the reflection ability.
Наземната лазерна система успешно улови лазерните ехо фотони, отразени от сателитния рефлектор DRO-A чрез оптимизиране на точността на насочване на телескопа и изключително слабо разпознаване и обработка на сигнала .
Съответната технология може да подкрепи спътниковия спътник в моята страна и измерването на разликата във времето на разстоянието между Земята и Луната и дори дълбокото пространство .
In the future, the research team will organize more astronomical observatories to participate in the observation, continue to improve the performance of the ranging system, optimize the design of the single-corner cone reflector, and further consolidate my country's technological advantages in the field of Earth-Moon space exploration.
