Dual-Frequency Gps: Ukraine's Tactical Edge in Drone Warfare

The article describes how Ukrainian forces have countered Russian GPS jamming by adopting dual-frequency GPS technology. While Russia deployed jammers targeting the standard L1 frequency band (1575.42 MHz) used by civilian GPS receivers, Ukrainian forces adapted by incorporating dual-frequency receivers using the L5 band (1176.45 MHz). About 73% of Ukrainian reconnaissance drones now use this technology to maintain positioning accuracy despite intense jamming. Rather than using expensive military components, Ukrainian volunteer engineers repurposed dual-frequency GPS chips from consumer smartphones and sports watches. These systems maintain positioning within 3-5 meters even under heavy jamming and reduce positioning errors by up to 60%. This adaptation has fundamentally altered the conflict by preserving Ukraine's drone reconnaissance capabilities. It has sparked interest from NATO and commercial sectors in dual-frequency technology as a cost-effective counter to sophisticated jamming systems.
