Tests Suggest Russian Satellites Can Jam GPS On a Continental Scale

Researchers say mysterious, seconds-long GPS interference bursts detected across Europe appear to come from Russian EKS early-warning satellites, making this “a rare example of human-made GPS interference coming from space,” reports Ars Technica. The signals may be tests of space-based jamming capability, short satellite communications, or something else, but experts say they raise troubling questions about whether GPS disruption could eventually be weaponized on a continental scale. From the report: The discovery came from an investigation detailed in a June 2 preprint paper by Todd Humphreys
