US Urged to Shift to LEO Navigation as Jamming Incidents Jump 62%

More than 1,100 vessels in the Strait of Hormuz logged GPS and AIS interference in a single day, underscoring warnings that U.S. reliance on GPS leaves military and civilian systems exposed.
Roughly 430,000 aviation jamming and spoofing incidents were recorded in 2024—up 62% from a year earlier—while the report argues GPS cannot be fully hardened because its medium-orbit signals are inherently weak.
Commercial U.S. low Earth orbit providers are presented as the near-term fix, with signals up to 100 times stronger than GPS, centimeter-level accuracy and compatibility with existing receivers, often through software updates.
The Space Force already canceled its planned $1 billion Resilient GPS constellation in favor of commercial services, and the House's fiscal 2027 defense bill would require demonstrations of GPS-free operation, anti-jamming performance and rapid recovery.
The report calls for a dedicated 2027 budget line, procurement of navigation as a service and tougher resilience standards for critical infrastructure, arguing China is moving faster to dominate next-generation navigation.
