'It's quite a bit more than we expected': Satellite reveals immense scale of GPS signal tampering
Summary
Space.com reports on Pulsar-0, a test satellite from Xona Space Systems, mapping GNSS jamming across Europe and the Middle East. The results show significant GPS signal degradation at satellite altitude, raising concerns about the reliability of positioning, navigation, and timing (PNT) for critical infrastructure and space operations. The piece also discusses jamming, spoofing, and solar-storm disruptions as ongoing threats, and notes Xona’s goal of a more resilient PNT with a future Pulsar constellation.
