Poland has been experiencing increasing disruptions to satellite navigation systems, including GPS, this summer, according to data from a monitoring station operated by Poland's National Institute of Telecommunications.
The data, which was provided to the Polish Press Agency, showed prolonged interruptions affecting all global navigation satellite system (GNSS) bands over the last few months.
Anomalies have been recorded regularly since January 2024, but since the beginning of 2026, their frequency and intensity have risen sharply.
In May and June, significant, long-lasting disruptions across all GNSS bands were recorded on around 70% of days. Days completely free of interference accounted for just 10% in May and 13% in June.
In the first 19 days of August, full-scale disruption was recorded on 63% of days in the month. In other words, navigation on smartphones and civilian receivers suffered issues, on average, on roughly every two out of three days.
