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. > > -----Original Message----- > From: NANOG [mailto:nanog-bounces+emille=abccommunications....@nanog.org] > On Behalf Of Allan Liska > Sent: December-30-16 11:09 AM > To: Majdi S.
