2026 counterspace report: GPS jamming incidents surge as Russia and China target Starlink and LEO navigation
Breaking Defense reported on a fresh counterspace assessment showing GPS and LEO signal-jamming incidents climbing sharply, with Russia and China expanding electronic warfare against commercial navigation and communications assets. Russia's
Analysis
GPS jamming across Eastern Europe, the Middle East, and contested maritime chokepoints has shifted from event-driven to ambient: a structural exposure rooted in commercial LEO architectures built on cooperative GPS assumptions that no longer hold near contested airspace, per a single Breaking Defense report citing an unnamed assessment whose figures should be read as trend indicators rather than calibrated counts. Starlink's beam-steering dependency on GPS time-and-position remains almost certainly a targeted vulnerability through year-end; Russia's Kalinka and demonstrated Iranian variants have already been validated against deployed terminals, and alternative positioning through inertial chains or multi-GNSS switching adds engineering complexity without closing the gap. Downlink degradation may instead prove localized and manageable through narrow geofencing, predicting operator outages staying below five percent of beams over contested regions, but roughly 10,000 annual interference incidents tallied across commercial satellites suggest the exposure is broadening rather than stabilizing.
