Drone makers race to build navigation that survives warzone jamming
TL;DR
GPS jamming in Ukraine is driving demand for alternative drone navigation. Q-CTRL (quantum), ASIO (vision), and ANELLO (laser gyro) showed solutions at Farnborough.
GPS spoofing and jamming have become standard countermeasures on the battlefield in Ukraine, separating drones from their operators and rendering some guided munitions useless. US-made Excalibur artillery shells fell out of favour after initial successes because their GPS guidance was jammable. Even fibre-optic control wires have been countered by entangling lines strung across fields. The result is a rush of companies building navigation systems that work when GPS does not.
Three showed their solutions at the Farnborough International Airshow this week. Australian company Q-CTRL uses quantum measurements of the earth’s magnetic and gravitational fields to keep drones on course in GPS-denied environments. “The technology is not a replacement for GPS,” said Charlie Burnard, Q-CTRL’s global head of government engagement. “It is a reliable,...
