GPS Denial Events Affect Iridium Services and Boeing 737 Performance
What happened
GPS denial events were reported across Eastern Europe, the Baltics, and the Levant on October 15, 2026. Analysis shows that GPS degradation tail-days rose from 40,000 in August 2025 to 80,000 by the end of July. The interference has affected Iridium's position, navigation and timing services and degraded the performance of the Boeing 737 family.

Why it matters
The increasing threat of GPS denial drives demand for countermeasures, such as the M100 unit being developed by Skyband Systems, which integrates Iridium's low Earth orbit PNT service with inertial sensing. These incidents highlight operational risks for aviation in conflict zones.
