TLDW: Russia is jamming GPS and GNSS over Europe, purposefully, using a constellation of military satellites.
Theory is that Russia is constantly practicing to totally disrupt GPS and GNSS (and the Chinese system) across all of Europe.
- floxy 5mo agoAnyone have a good source to read up on the current state of the art for daytime celestial navigation? Maybe there isn't too much in the public domain, because things like GPS work so well. But I'd guess that since you can't easily artificially jam celestial navigation there would be military research on this. But I suppose clouds also limit the practicality as well. https://www.scientificamerican.com/article/how-to-see-stars-satellites-and-more-in-the-daytime-sky/ https://www.scientificamerican.com/article/how-to-see-stars-...

The fourth global GNSS constellation is Europe's Galileo. NavIC and QZSS are regional GNSS constellations.
