Lee knows way more about machine control than I do, or than I want to learn. But, all the people I give control to that use machine control calibrate ...

You either imported or keyed-in your coordinates into a job file setup as local ground datum. Then you changed the datum to a state plane projection a...

No need for RTK, just use PPK. Can use your base or any near by CORS collecting static at 1hz.

I suggest you not rely on OPUS for vertical as they only use GPS data, not GNSS. If you have GNSS recievers send me your rinex files (or TPS) and I pr...

Several terrestrial scans and control points with robot. Then cut 3d sections every 25ft or so.

I'd find a suitable college where I could teach surveying and construction layout.

When did Shawn leave Javad? Wondering what he is doing now? Back in practice?
