China's satellite uses rare US-scarce metal for global surveillance

By PulseAugur Editorial · [1 sources] ·

China has launched a high-orbit satellite, Ludi Tance-4 01A, that utilizes gallium nitride, a rare metal for which the United States faces supply challenges. This satellite operates in a geosynchronous orbit, enabling continuous surveillance of a significant portion of the Earth's surface, a capability the US has pursued without success. China's dominance in the global supply of gallium nitride, largely a byproduct of its vast aluminum production, underpins this technological advantage. AI
