Transportation For America

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.

Transportation Secretary Sean Duffy, joined by major airlines, is urging Congress to approve roughly $30 billion to modernize America's air traffic control system. The appeal targets aging equipment and staffing shortfalls that have contributed to delays and safety concerns across US airspace. The push puts funding for controllers, radar and communications technology on Congress's agenda, with airlines backing the investment to reduce disruptions for travelers.
