Washington, June 7: US lawmakers issued a stark warning this week about the potential economic fallout from a successful attack on the Global Positioning System (GPS). During a committee meeting in the House of Representatives, discussions centered on the rising threats from China and Russia, as well as alternative technologies that could serve as GPS backups.
Members from both parties acknowledged that GPS has become an integral part of daily life. They noted that the increasing incidents of GPS signal jamming and spoofing pose significant risks to national security, transportation, communication systems, and critical infrastructure.
Chairman of the House Energy and Commerce Subcommittee, Richard Hudson, emphasized that GPS is no longer limited to navigation apps. It plays a vital role in various sectors, including communication, energy, financial transactions, and emergency services. He stated, “If an adversarial nation jams or spoofs GPS, leading to a large-scale system failure, the impact on our economy could be devastating.”
Hudson highlighted that Russia and China are developing capabilities that threaten satellite-based services. He referenced a recent incident where a British military aircraft lost its GPS signal due to alleged Russian jamming.
Senior subcommittee member Doris Matsui pointed out that American citizens often underestimate their reliance on GPS. She explained, “GPS helps power your internet, facilitates digital payments, and secures your bank accounts from fraud. It also aids emergency services in reaching you when you call 911.”
Matsui warned that significant disruptions to GPS could affect communication networks, aviation, the energy sector, agriculture, and supply chains. House Committee Chairman Brett Guthrie noted that these threats are already evident abroad. He remarked, “Our adversaries are jamming and spoofing GPS in conflict zones, increasing risks for our troops. If GPS is disrupted in the US, the economic consequences could be severe.”
Experts at the hearing informed lawmakers that while GPS remains reliable, the US must develop a more robust and multi-layered system for positioning, navigation, and timing services. Lisa Dyer, Executive Director of the GPS Innovation Alliance, described GPS as “one of America’s greatest innovations.” She noted that since its inception in 1995, there has never been a major system-wide disruption. Currently, the GPS network consists of 32 satellites, boasting a 99.99% availability rate.
However, Dyer also mentioned that local jamming and spoofing incidents are impacting aviation and maritime services. She called for modernization of the GPS system and stricter actions against illegal interference.
Several experts supported the development of alternative and complementary systems that could function even when GPS signals are disrupted. Sam Matheny from the National Association of Broadcasters discussed the Broadcast Positioning System, which utilizes existing broadcast towers and licensed spectrum. He stated that this system was developed to mitigate the economic and national security risks exceeding $1 billion daily due to over-reliance on GPS.
Mariam Sorond, CEO of NextNav, warned that the US remains vulnerable as it lacks a ground-based backup network for GPS. She noted, “China and Russia have established land-based backup systems for GPS, but the US has not.” She referred to GPS as a “national treasure” but also a “single point of failure.”
The hearing also revealed disagreements over proposals related to the 900 megahertz spectrum band. Consumer organizations, tech companies, and industry representatives cautioned that changes could disrupt existing services used in electricity, public safety, retail, transportation, and agriculture.
Lawmakers repeatedly stressed that any new backup system must undergo extensive testing to ensure it does not impose additional burdens on consumers while safeguarding existing services.
Originally developed by the US military, GPS was later made available for civilian use. Today, billions of people worldwide rely on it, making it essential for aviation, telecommunications, banking, logistics, and modern agriculture.
