Flying at roughly 500 km altitude, the satellite found normal signal strength around 40 dB dropped to about 10 dB in the most heavily jammed areas. The worst interference appeared from Northern Europe through Russia, Ukraine, Turkey, Iran, and Pakistan. Xona co-founder Kaz Gunning said the team expected interference but it was much larger than expected.\u003c/p\u003e\u003cp\u003eNear Russia\u0026#39;s western border, jamming is reportedly used as a countermeasure against Ukrainian drone attacks, affecting tens of thousands of aircraft each month. In the Middle East, jamming and spoofing are used to deflect drone attacks or hide illegal vessels at sea. The interference also threatens satellite operations: low Earth orbit satellites that lose GPS struggle to determine their position for imaging, track their own location, and orient toward ground antennas. Starlink and similar constellations rely on GPS for collision avoidance.\u003c/p\u003e","blueskyPost":"Xona Space Systems' Pulsar-0 satellite data reveals GPS jamming near Russia's western border is far more extensive than previously documented.
