I've contacted them about doing a quick test. They won't have any of that model in the US until the end of April. Trying to arrange meeting them at a conference and setting up a test area nearby. Will post as soon as we have any data

I guess I'll be holding off on an new RTK unit for a couple months. It sucks we're still buying new data collectors running soon to be obsolete and no longer supported Windows 6.5 Mobile. 

It was bound to happen, how soon before Carlson writes SurvCE app on Android?

Engine (I think): https://www.u-blox.com/en/product/zed-f9p-module

Gavin: Are you going to get a pair or a net-rover? (I volunteer Mr. Robot to test on, try to get a serial cable.)

Antenna Calibration: relative or absolute?

Radio: FCC Certified yet?

So many unknowns at this point. Will ask all of those. 

First look will be at a conference at the end of April when they have will have a pair on this side of the pond...

Both very skeptical and somewhat excited at the same time...

Were you able to meet? Or is there an NDA...

Have not been able to get a hold of some to try out. One of their staff is in the US for some conferences, and we've arranged for a surveyor bud who will meet him at a conference later this month to do a quick test out in the parking lot (simple inverse comparisons). If it looks like it truly can do survey grade, then will get two to do more formal testing. Chip specs look good; cautiously excited...

Will be trying out another low-cost option soon from an outfit called Tersus... there is a whole wave of low cost rovers on the horizon...

Yeah, Tarsus even have a basic 'survey' Android app called Nwua... which will also work with NMEA.

Yep. Looking forward to trying out their 'David' base-rover pair. Awaiting shipment. Chip and antenna specs look great, but like any new gear: cautiously excited.
