Going off of my experience with the previous RTK module: 6mm precision... if you're standing perfectly still. But cm-scale at high update rate is quite the leap over the previous gen which was accurate to about a meter when the receiver was moving.
This looks amazing. I jumped in to order one then I saw the price. It is probably great value for money but it's way too much money for something to just have a play with!
Cool tech, I wonder what usage case is this good for... Needing that much precision and that much range! Kinda overkill for my usage case (land surveyor rover)
Do you have anything that summarizes the value-proposition of this compared with your UM980 breakout (i.e., GPS-23286)? It seems they both do useful combinations of concurrent tri-band. Aside from self-contained web config & logging, and some performance increases (e.g., 6mm RTK vs. 8mm, 100Hz refresh vs. 50Hz), what are some other big differentiators?
I guess that I am out of date on Sparkfun's target market. For me, I would prefer to see products that wouldn't require the level of purchase justification this one would. In other words, it is certainly amazing what is available if you don't care about cost.
