For photogrammetry we start at roughly $3,500/day for field data acquisition, depending on travel. That includes ground control, check points, and ima...
Haven’t done RTK but tested PPK, short story…still need GCPs. PPK might screw it down to a foot or two but that’s about it. Any chance you have ...
With my WingtraOne PPK I rarely need GCPs. Most of the time I put out targets only for checkpoints. Horizontal rms is 1x gsd and vertical is 1-1.5x gs...
Fyi, here is my Master's Report that I did using the Wingtra.?ÿ Horizontal accuracy of 0.05' and vertical accuracy of 0.15' with no ground control.?ÿ ...
I agree 100% about DJI.?ÿ Good products, but will never be on the DOD approved list.?ÿ The Wingtra is on the Blue sUAS list: DOD Blue sUAS List

I've owned a Wingtra for two years. It's an amazing aircraft that excels with large area surveying and mapping. At 400ft agl, with the 42mp Sony RX1RI...
@mightymoe I've also tested the Delair UX11.?ÿ While not quite as accurate as the Wingtra, it was still pretty good without GCPs.?ÿ It was within 0.2...
@mike-marks I'm a licensed engineer (civil) and have my GISP, so I feel I'm qualified to discuss this topic.?ÿ I believe the GISP is a well-intention...
@mightymoe Using RTK for check points, I always get 0.15' or better (usually <0.10') with 0 ground control with the Wingtra.?ÿ It's quite impressi...
@chris-mills Certainly the accuracy of the point cloud varies greatly with terrain type.?ÿ That is not what I'm trying to test in this project.?ÿ I'm...
@stlsurveyor In P4D, if you process Step 1 first, then it makes identifying the targets in Ray Cloud extremely easy.?ÿ With PPK, the cross-hair is wi...
@chris-mills I'm only using the targets as independent check points.?ÿ All of the processing will be performed with PPK processed geotags only (x, y,...
@mightymoe The gsd of the Wingtra / Sony Rx1RII at 400' agl is 0.05ft.?ÿ I'd like to see how close I can get to that.?ÿ This will be an interesting e...
@dmyhill I spoke with my local Trimble sales rep today.?ÿ Although he's not a PLS, he has a lot of surveying experience prior to becoming a sales rep...
@andrew-clark Thanks, I'll look into that.

@jitterboogie The WingtraOne has a 42mp Sony RX1RII full-frame DSLR camera. It can achieve 0.025?? gsd at a flight altitude of 200 ft agl. I typical...
@spmpls Thanks for the information. I will keep an eye out for the paper. My project is much smaller and focused on my specific drone. I am taking th...
