GPS Down? China Turns to Celestial Navigation for Hypersonic Weapons

China is giving its hypersonic weapons an unusual navigation backup when satellite signals fail.

Researchers at the Guangdong Aerospace Research Academy have reportedly developed a self-contained, star-based navigation system that can operate without relying on satellite signals or electromagnetic inputs.

The tech works by tracking the apparent movement of stars to determine a vehicle’s position and motion during flight.
