I was casually (yes, really) looking around at some GNSS modules available
the other day, and readily found quite affordable ones that can receive at
least 2 at a time, of those systems.  GPS and GLONASS being the most
complete, so probably the best bang-for-the-buck.

I'm only an armchair time-nut, so I can't really speak to their precision
and such, so this is very much a FWIW post.
