China's Gallium Nitride Satellite Monitors Asia Pacific
China has launched a special satellite called Ludi Tance 4-01 that can watch over a big part of the Earth all the time.
This satellite uses a special material called gallium nitride, which helps it work really well from a very high altitude.
No other country has this material because China controls all of it.
The satellite can see a lot of area because it is very high up, but it needs a lot of power to work.
China has restricted the export of gallium nitride since the satellite was launched in 2023.
China's Ludi Tance 4-01 satellite uses gallium nitride for high-performance radar.
The satellite operates in geosynchronous orbit, allowing continuous monitoring of the Asia-Pacific region.
Gallium nitride enables the satellite to generate strong radar signals from a high altitude.
China has a monopoly on gallium nitride, restricting its export since 2023.
The satellite's amplifiers generate 18,000 watts of power with 50.3% efficiency.
