GPS technically only refers to the system established by the US, whereas GNSS is a general term including Beidou, Galileo, and GLONASS. (any others?).

Two questions use and five questions use the more general .

While GNSS is the more general term, many users may still search for a GPS tag because the term has been around so long it's used (incorrectly) interchangeably with GNSS in popular context.

I've made sure the two posts that have also have so that they could be synonymized. That way when people type GPS they will see GNSS as the option.

I've made an edit to update the Wiki excerpt which is currently pending.

Global Navigation Satellite System, including GPS, GLONASS, Galileo and BeiDou

Question: Would it make sense to use as the tag for all related questions, and convert GPS to a synonym? If so, what would be required?


I agree with you. What should be done is to merge the tag GPS to GNSS, so all GPS tags are changed by GPS. However, I would keep GPS as a tag synonym.

GPS have its own meaning but I think most questions are related to GNSS and not particularly to GPS. And as most people identifies any GNSS system as GPS I would leave it as a synonym. Other tags like Navstar can be crated to refer specifically to the US GNSS system.

As for the merge. It has to be done by a moderator, and I think there are several other merges that need to be made. Perhaps we can make a list of them so the moderators can do all in one go.

It leads to all the goodies. meta.stackexchange.com/a/70718/303080 I'm not sure but what might be needed to do this is one or two more question that share both tags, I think with four or five, the process becomes easier? $\endgroup$ – uhoh Apr 6 '19 at 23:49

I do not have the english word for what I try to explain, but this is a special case. At Europe, note I am not american, I truely didn't know what is GNSS until now. GPS is a ...(the word I don't find).... for every system that uses location via satellite, so it is what the posters, mosts of times, gonna tip for. Sunday 14 when I tip GPS GNSS is not showed in the list. It should I agree with that.

Maybe the experts you know it is the acronym for american project, but you can always edit the post including GNSS if it is more accurated.

  • $\begingroup$ Thanks for your answer and for sharing your experience. I think then you agree that when people start typing GPS an option should appear immediately, because for some people GPS is the term they use for all GNSS. Thanks! $\endgroup$ – uhoh Apr 16 '19 at 4:05
