When GPS Goes Dark: Building a Force That Navigates from Orbit to Seabed

GPS denial is no longer a theoretical future threat. It is the environment in which modern forces increasingly operate.China has invested heavily in space and counterspace capabilities designed to degrade U.S. positioning, navigation, and timing. Other state and non-state actors are following close behind. Cheap jammers, spoofers, and electronic warfare tools now allow adversaries to disrupt GPS and radio frequency navigation with minimal funding or expertise. The result is a battlespace where signals cannot be assumed.From space-based mapping of interference to fiber-optic drones appearing on today’s front lines, the evidence is clear: the electromagnetic spectrum is contested, fragile, and increasingly
