A Chinese communication and navigation technology test satellite, known as the Tiandu-1, has recently conducted a laser ranging technology test in the Earth-Moon space under strong daylight interference conditions, marking a world first, according to the satellite's developer, China’s Deep Space Exploration Lab (DSEL), on Tuesday.
This achievement represents a major technological breakthrough for China in the field of precise measurements in deep space orbits.
Laser ranging on satellites in the Earth-Moon space is akin to targeting a single hair from 10,000 kilometers away while performing precise tracking and signal capture. In the past, such tests could only be conducted at night when light interference was minimal.
The successful daylight laser ranging test has effectively expanded the observation window, providing crucial support for major deep space exploration missions, such as the International Lunar Research Station.
The Tiandu-1 and Tiandu-2 satellites were launched into space alongside the Queqiao-2 relay satellite on March 20, 2024. They entered their target circumlunar orbits on March 29 and separated on April 3. The Tiandu-1 has already completed multiple new technology tests in orbit.
