Essentially all questions currently tagged gps-navigation are not specific to GPS, but apply to all GNSS, including GPS, GLONASS, Galileo, and others. Many users may not even be aware which one of those technologies the GNSS in their device supports. Therefore, I propose to rename the tag gps-navigation to a more appropriate gnss-navigation (or just gnss), and make gps-navigation a synonym thereof.
I'm well aware of the different satellite constellations, who launched them and why GNSS is different from GPS, yet I routinely use GPS to refer to any part of the system in any context except where the more detailed knowledge is appropriate. It's the commonly accepted term where I live, and would be the first term I'd search for unless I was looking for, say, GloNass, or Galileo in which case I'd search for those, and still not use GNSS.
We should leave things alone.
