America runs on GPS. It needs a backup plan
The United States relies heavily on GPS for navigation, transportation, communications and financial systems, leaving critical infrastructure exposed if satellite signals are jammed, spoofed or knocked out. Policy analysts are renewing calls for backup timing and navigation systems, including terrestrial alternatives, warning that a GPS outage could disrupt daily life and national security across the country.
