Without Glasnos most of the land surveyors in this country would be SOL. Our GPS is not sufficient to operate in high foliage areas. With glasnos, RTK (you know those surveyors you see with a pole with an dome on top) would be limited to mostly open areas. I don’t own GPS because I never wanted to be dependent on .gov for my work.

It’s actually called GLONASS, and those TOPCON Hyperlites you mention depending on model can receive GPS only, or GPS+ GLONASS, or GPS+ GLONASS+ Eurostar.
Our GPS is able to be used in high foliage areas! BUT you need to use either a military grade receiver such as the PLGR, or a professional grade receiver such as the Hyperlite.
We’ve battling at work over our GPS enabled handheld devices which are +\- 50ft accuracy. So now we got saddled with an additional Garmin that is GPS + GLONASS which gives us a +\- 20ft. In both cases we’re using “recreational grade” equipment while the client was promised professional grade results by our higher ups while people like me who make things happen get stuck in the middle of the circular firing squad.
I have some compasses and USGS maps. I got a GPS for Christmas a while back and I think it is in my hunting backpack and I would use it only to mark a precise location (like a kill) to return to it expeditiously.
