Russia’s Space-Based GPS Jamming Confirmed by Independent Research
UT Austin researchers, corroborated by others from the UK, used data from 165 GNSS reference stations to confirm that Russia has been jamming GPS from space since 2019 via a small Molniya-orbit satellite constellation, causing short, powerful disruptions on the L1 band (up to about 10 dB CNr) and also impacting BeiDou. The 2025 study and a May 2026 preprint argue the pattern is intentional rather than a malfunction. The findings underscore GNSS vulnerabilities, spur terrestrial backup efforts by several countries, and highlight policy and strategic implications for space-based EW in great-power competition.
