United StatesThe National Nuclear Security Administration (NNSA) is upgrading blast detection sensors on GPS satellites to improve the ability to monitor nuclear explosions globally. These upgraded sensors, known as the next-generation Global Burst Detector system, are being prepared for deployment on new GPS satellites. The upgrades come amid concerns over rising nuclear threats from countries like Russia, China, and North Korea, which are expanding their nuclear capabilities. The new sensors use advanced technology called SIGHTS to enhance accuracy and reduce false alarms. They will be installed starting in 2028 on all new GPS satellites produced by Lockheed Martin, with plans for up to 22 launches by 2037. The improvements aim to ensure continuous 24-hour monitoring of potential nuclear detonations and support national security efforts.
