China operates the Ludi Tance-4 01, a radar satellite described as able to provide continuous surveillance over a large portion of the Earth. Reporting based on a newly disclosed study says the satellite stays in geosynchronous orbit at about 36,000 kilometers above the planet, allowing it to remain fixed over the same geographic area and conduct monitoring without switching positions frequently. The satellite is reported to cover roughly one-third of the Earth’s surface and is characterized as providing 24/7 surveillance. The studies and coverage also link the satellite’s functioning to gallium nitride (GaN) semiconductors used for its power and electronics. Multiple outlets emphasize that gallium is a key input for GaN and that global supply of relevant materials is dominated by China, while the United States faces difficulties obtaining them. This combination—geosynchronous placement plus GaN-based components—is presented as part of why the satellite is described as unique among similar systems. The accounts focus on technical capabilities and supply-chain dependence rather than operational details or specific targets.

- China’s Ludi Tance-4 01 radar satellite is described as able to provide continuous surveillance.
- It operates from geosynchronous orbit at roughly 36,000 km above Earth, allowing it to remain over the same area.
- The satellite is reported to cover about one-third of the Earth’s surface.
- It uses gallium nitride (GaN) semiconductors as part of its electronics/power system.
- Coverage highlights that gallium/related rare material supply is dominated by China, with the US described as having procurement challenges.
Ludi Tance 4-01 is powered by gallium nitride semiconductors, enabling constant surveillance over one-third of the Earth’s surface.
1 day agoA satellite that can provide 24/7 surveillance of a third of the Earth’s surface relies on a rare mineral whose global supply is dominated by China, a new study has disclosed. The Ludi Tance-4 01 radar satellite, powered by gallium nitride (GaN) semiconductors, is the only satellite of its kind. It orbits 36,000km (22,000 miles) above the Earth and is able to stay in what is known as a geosynchronous orbit, which keeps it fixed over the same spot. This allows it to monitor both large areas of...
