Poland has experienced severe and increasing disruptions to satellite navigation systems including GPS throughout 2026. Monitoring data from Poland's National Institute of Telecommunications and independent companies like Blue Dot Solutions show prolonged, multi-band GNSS jamming and spoofing affecting civilian and military users. The disruptions have caused loss of positioning accuracy on smartphones, urban transport systems, drones, shipping, and aviation, including confirmed GPS jamming of the Polish minehunter ORP Albatros on 21 August 2026. The source is linked to electronic warfare systems active in the Baltic Sea region, notably from Kaliningrad, which has significantly expanded its spoofing infrastructure since 2025, covering an area up to 450 km radius that includes much of Poland and neighboring countries. Baltic and Nordic nations report similar interference incidents in their airspace and maritime zones, with NATO increasing countermeasures. Poland is developing resilient navigation monitoring networks. Russia is widely attributed by Western officials to be responsible, with claims that jamming is to counter Ukrainian drones. High frequencies of full and partial GNSS interference days were recorded in May, June, and early August 2026, with partial disruptions affecting a dozen to 30% of days and full disruptions 63-70% of days. The incident continues ongoing and systematic.
