That’s what I said “CHEAP RTK GPS” !
This project showcases some students and I working out the details/testing a new Base/Rover Combination using Emlid’s new (to me anyway) devices called reach RTK. (entire kit for a base and rover here) Kit costs $570 that’s what I said! Cheap RTK GPS !
The students and I ran some test points laid out using our total station, accuracy was within 2 cm (some closer to 1cm) on each point.
Total Cost including all parts, less that $1,000.00
