Ditto that. Static ONLY for control.
Using the Leica SmartRover GPS unit, I occupy a control monument, record three shots, then break the lock and record three more checking the residuals. Then, as a check I will occupy a different control monument and repeat. If my diff. in X,Y,and Z check I then go to work.
me too, I use the RTK so little I forget how to do it. But a lot of our control isn't GPSable to GPS is only a supplement.

You must not ave a good VRS available, I shoot traverse control with RTK all the time, works well.

You're right there. At least until they make a VRS that covers 15 states including the boonies where there's not even cell coverage.
From what I've seen (in this area), VRS is very sloppy.
:coffee:
I use the total station for control and building ties, and the gps to tie in with the traverse control....So, I don't use GPS for control without ties with the gun. Most of my control is under canopy anyway...
So, occupation time? About 5 seconds, three different times during the topo...

I ran a test in our parking lot. The results of two 4 hour OPUS sessions on a point bracketed a single 1 minute RTN session. I'm pretty confident about Oregon's RTN when the site conditions are good.
The problem with RTN, for control, is that you don't get a lot of statistics that tell you when conditions are good.
I use RTN when my purpose is to put a project on a state plane basis so it conforms to GIS data, or just to reference my topo to the network control. If I were running geodetic control, I'd use static. Thing is, if you can put your project on state plane this way, the need for geodetic control is greatly reduced.
Were you using the ORGN during your test?
