GPS spoofing to redirect drones also corrupts GPS for friendly vehicles within the radius

GPS spoofing broadcasts a stronger fake GPS signal to trick a drone into flying to a wrong location, but affects every GPS receiver within the spoofing radius (500m-5km), meaning friendly vehicles, precision munitions, and civilian aircraft all receive corrupted position data simultaneously. In one documented incident, GPS spoofing near a Russian military base shifted commercial aircraft positions by 25+ nautical miles. This persists because GPS is a one-way broadcast protocol with no authentication at the receiver level -- there is no way to broadcast a fake signal that only affects hostile drones. Military M-code receivers are protected, but all civilian receivers remain vulnerable.
