Are those guy wires? or, are they stiff rods, like tent rods? I had the wind blow my base antenna flat, bending up the tubes... I cannot elevate it as tall now...
Typically, If you return to the truck, and open doors, etc, then you are not surveying at that moment... so the motion does not matter.
I have worked in Chicago, when the wind would nearly pick up the vehicle. But, what would that do with a tripod setup?

Assuming that you have done some sort of study, what sort of movement do you get at the top there? (Wind, getting into and out of the truck, etc.)
I use this set up for basically all of my gnss work. I try to park on pavement, thats ideal. I haven't really noticed any problems with wind. Unless you have a tire going flat or something the receiver will return to the place it was when you get in and out.

Nate, they are prism poles mounted to my truck bed. The cables are for theft protection and lock to the radio and reciever.

Well, I guess that is my question, why would you do this at all with Network RTK so widely available?

All the receivers I have worked with allow for static data to be recorded while operating as a base, perhaps if you turned on that feature, you could determine the ellipse of movement. I suppose that the vertical would be negligible (especially considering it is RTK). If you were doing all raw ground topo, I cannot imagine it would matter too much. Personally, it would make me a little nervous for boundary or ALTA or any control work.

Saves the data plan and I like having a base close to the project. 5Hz broadcast corrections are not available on a RTN, that is the reason I prefer a local base.

Really the truck doesnt move that much in the wind, if it's that windy and I had the cell coverage I would probably opt to use the network only.
Well, I'm not in Chicago now. I'm in Arkansas.
And, as far as rtn networks, the only one I can think of, is city hall, in Glenwood. They "Real Time Network" with their buddies, and it keeps things small town interesting!
Even with an rtn, it won't operate in Beast Mode.... And, I truly like Beast mode!
