Thanks for explanation. I had absolutely no awareness GPS jamming was a thing, let alone at scale.

The United States (who created and operates GPS) also has the ability to make civilian GPS receivers in a specific area or region area less accurate, in case of war. I would assume that other countries' systems (Russia, China, maybe not EU) also have this ability.

GPS was primarily developed as a military technology. It was intentionally inaccurate for all civilians up until the year 2000.

		Most of the time people say “GPS” they really mean any of the several GNSS systems, which also include: GLONASS, GALILEO, QZSS, and BeiDou While they’re all susceptible to jamming, one system getting shutdown by its operator means most modern devices can shift to the others for most applications. Not unusual for consumer devices to support multiple (but dunno how they handle disagreements) https://en.wikipedia.org/wiki/Satellite_navigation_device https://www.xda-developers.com/apple-iphone-14-gps-support/#...

my runner friends hate it, suddenly your Garmin can't show your pace and distance properly. (I am very much aware it's a 1st world problem to have in times of war)
