I noticed that we seem to have two tags for the Global Positioning System: [gps] and [gnss-gps]. These two tags seem to have exactly the same meaning—namely, the Global Positioning System, which is a particular global navigation satellite system (GNSS).

I don't see any reason to keep the [gnss-gps] tag.


I agree, furthermore I'd recommend renaming the tag to the generic , to cover the rest of the constellations.

By 2020 the total number of GNSS systems should be 4: GPS, GLONASS, BeiDou, and Galileo.

    $\begingroup$ If we rename, then I'd highly recommend making gps a synonym of gnss, as I expect far more people will be trying to tag questions gps than gnss. I'm not sure, though... is it really ideal to have only one tag for all 4 systems rather than separate ones? Are they similar enough that this is a reasonable thing to do? $\endgroup$ – reirab May 16 at 22:02
  • $\begingroup$ Old a/c receivers are GPS only, quad constellation receivers will be the norm. IMHO most people are not aware which constellation(s) they are using, and they don't know the term GNSS. Synonym or not, some existing questions will end up with the wrong tag. In addition, when gps is synonym with gnss, there is no specific tag for the GPS system. $\endgroup$ – bogl May 17 at 7:02
  • $\begingroup$ I think it doesn't really matter if gps is renamed to gnss, and a new gps is created, or gps stays as is, and a new gnss is created. Either way, it will be a bit messy. Either way, we should end up with [gnss] [gps] [galileo] [beidou] [glonass], because it seems logic. To me, at least. Time will tell if people are using all 5 tags. $\endgroup$ – bogl May 17 at 7:06

I want to express that ymb1's answer got my upvote, but that I have one reservation which I thought was worth putting here as an answer so it can be voted on and commented as appropriate.

I agree that the current tag should be renamed to . However, I have a reservation about separate tags for the other systems - mainly that colloquially most people know the name "GPS" and will tag as such when what they really mean is the more generic "GNSS". I also do not think we will ever get enough questions about a specific system (such as "GLONASS") that would warrant having separate tags. And even if a question is about a specific system, tagging with is still useful.

Therefore, my suggestion is as follows:

Note that earthscience.se seemed to agree with my point regarding the colloquial use of the term "GPS".

  • $\begingroup$ Fully agreed. Also note I did not propose separate tags. The regional tag + gnss was deemed too complicated and has since been removed. $\endgroup$ – ymb1 May 22 at 16:57

I agree that there's no reason to keep the tag.

My thinking would be that questions about GNSS in general should be tagged and questions about a specific system should be tagged with that system's name.

Alternatively, we could make the specific system tags be synonyms of , but I really don't see the need to do that at present. I think it's fine to have both a generic tag and specific ones for each system.
