Surveying around a NRQZ
Posted by just-a-surveyor on November 12, 2019 at 11:31 amSo I have been looking for a place to go do some really good trout fishing and I found the Greenbriar River flowing through east central WV. I also learned of what is called the National Radio Quiet Zone and got to wondering how surveyors might use GPS equipment.
I’m gonna have to look for some land up there. No cell phones would be glorious.

Think of all the chores that would get done without the wifi interference. That sounds like a good place to move to.

wondering how surveyors might use GPS equipment.
My guess is that static and PPK would be fine, as those are only receiving, but no real-time links for base-rover or network RTK. Even robotic station links to a data collector are probably disallowed.

It has multiple sub-zones with varying restrictions. In the most severe, even digital cameras and microwave ovens are not allowed because they may emit interference.
In that area even GNSS receivers might not be allowed because they use internal local oscillators that might emit.
.Question
is the QZ a QZ because it??s a research facility, like radio telescope? Or a commune of new age hippies?
If the former, I??d give it the respect it deserves, quiet has a definition.
If the latter, gps is passive for a reason: it??s stealth and has zero detectability.
Unless your base has a giant whip antenna as mine does that can reach out for a couple of miles.
From what I have read it is a quite zone for the interception of radio signals from foreign adversaries so the McDonald’s drive through probably has a tin can on a string.
I just think it is cool as all get out and I will be going there for some trout fishing. What could better than to be legally required to disconnect.
The question is are handheld GPS receivers off limits?
I only have post processed gps.
I did GPS work at Sugar Grove, but it was all post processed static. There were no restrictions given to me, but I was not so close to Green Bank. At the time I was not doing RTK, only static. Now I do more RTK but with cell rather than UHF radio. I will tell you that WV is one of the worst states for cell coverage, especially on the Verizon side (as opposed to AT&T, which is somewhat better there, so a lot of times RTK over cell in WV is problematic.
