The vulnerabilities of GPS are no longer hypothetical: jamming, spoofing and outage events are documented across aviation, shipping, energy and finance. The U.S. government has called for terrestrial complements to GPS through executive order 13905 and the National Timing Resilience and Security Act. A single day of GPS disruption could cost the U.S. economy more than $1 billion, according to a 2019 study by NIST. Merkhet Solutions is working to bring Broadcast Positioning System (BPS) to market to provide a terrestrial, GPS-independent solution for critical infrastructure.
Award-winning investigative journalist Brendan Keefe talks with experts about how U.S. critical infrastructure is over reliant on GPS. Hear from Bradford Parkinson, who developed GPS for the U.S. Air Force in the '70s and more recently served as vice chair of the National Space Based Position Navigation and Timing Advisory Board, where he warned of threats to GPS and called for a backup system to prevent an economic catastrophe.
