GNSS Jamming Spills Over into Europe’s Longest Sled Dog Race - Inside GNSS - RNTF Image: U.S. Air National Guard Senior Master Sgt. Julie Avery What's new: Yet another activity impacted by Russian jamming. Why it's important: A great

#GNSS jamming from Russia's Kola Peninsula is now disrupting GPS trackers at Europe's longest sled dog race — a stark reminder that satellite navigation underpins far more than aviation and shipping.

#GPS #GNSS disturbance/jamming ?

GNSS (GPS, Galileo...) guide our world & wars. Signals are fragile, easy to jam/spoof.
Dev's take: Weakness drives innovation (geopolitics helps). Consumer apps? Not the target. Real solution in war? Destroy the jammer. Brutal but real.
