10 minutes plus 1-minute per mile of Baseline. Distance between the occupied point and your longest vector to another occupied point or CORS in the ne...

Best to constrain on an original BM, then check into the CORS. They will almost be different, every time.Suggest you set a TBM where you have wide ope...

Correction: CORS will help you get on to NAD83 horizontal, but NOT on the vertical you want, Tidal Benchmark.

OPUS is not going to work for you. With those short baselines 1 hour is way more than enough static data. With L1/L2 GPS & Glonass in open sky, yo...

My suggestion is to use 5 static GNSS and occupy all 5 points simultaneously for 1 hour using fixed 2m poles. Or use a minimum of 3 and leap frog.Then...

Please explain by "one GNSS observation on those 4 points plus 1 Tidal Benchmark".Was this Static with a single receiver, or two? Do you have nearby C...

Roby,You can add Topcon to your list.I'm sure you'll get a taker on the no holds barred head to head GNSS challenge, but it won't come without a adver...

Is this Trimble?In this case I create the corrected calibration/localization manually. Most don't know how to do this, but it is preferred method.Will...

Sounds like one you has applied the GEOID, while the other has NOT.Newer software will use GEOID even in a site calibration. Tell him to disable GEOID...

I have met the OP (Cordgrass) in person.Just as his profile indicates, he is Licensed in LA.

Howie,What dealer did you purchase from? New York is split into two GEOIDS, where are you located?By default the GEOIDS should already be on your FC50...

Ease,Here is an FZ-M1 firmware update to improve the rain mode. Works much better now, but still triggers in the hard rain. Makes for a good excuse to...

Sounds like you and your family may have identified a Recognition of Acquiescence.

What year was the original survey?What did you find at those south corners?Are they original monuments?The edge of the plowed ground along west bounda...

I work with CAD files like this very often. There are many tricks to extracting a decent surface from the DWG. Feel free to forward the DWG to "lee at...

Good luck. That will barely pay for 2 days training.You can't get much of an EDM for that price. Maybe stick with a theodolite and steel tape, or pay ...

If it is the GEO model FC-5000, then you could add a SIM card for 4G modem, to access a network.
