Navigating GPS Vulnerabilities: Implications for US Economic and National Security

Beyond merely guiding Americans to their destinations, the Global Positioning System is essential to the United States’ electricity grid, financial markets, and wireless networks. First responders rely on GPS to locate individuals in distress. Many US military systems rely on the position, navigation, and timing (PNT) functions of GPS, and systems similar to GPS have been central to new forms of warfare such as drones and precision guided munitions.But current US GPS technology is 51 years old and grows increasingly fragile as new, more resilient American GPS satellites sit idle in warehouses. Hostile nations such as Iran and Russia frequently spoof GPS so that ships mistake their actual location. Airline pilots encounter GPS jamming in many parts of the world, especially near the Russia-Ukraine border. Perhaps worse, the US has no robust backup to GPS, which could prove catastrophic in a military conflict or a natural disaster.To explain the challenges facing GPS and how Washington can solve them, Hudson will host an event with several leading authorities on the system.
