Russia’s Space-Based GPS Jamming Confirmed by Independent Research
TL;DR Summary
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.
