GPS with RTK for under 10cm accuracy
For greater production in the field and precision leveling we use Starfire GNSS GPS-GIS with RTK sold by John Deere mounted on the hardtops of our John Deere 8295r tractors as you can see in the pictures. Auto steering, ground leveling, and specific application of fertilizer. That old International H tractor is how we used to do it, and we still use it some today.

Re: GPS with RTK for under 10cm accuracy
I have found it quite interesting that modern farmers have global positioning satellite receivers that are about fifty-times more accurate than most mariners have on their boats.
ASIDE: on the sidebar topic of old tractors: we live a mile or so from the site of the old Dearborn Motors Corporation facility for FORD NEW HOLLAND tractors. The buildings and testing grounds are no longer there. In its place are new high-tech buildings, shopping, and condominiums.

Re: GPS with RTK for under 10cm accuracy
Accuracy comes at a price. Starfire (John Deere) and OmniStar (Trimble) are subscription contracts with several levels of service down to 2.5cm if needed.
OmniStar is global and would work on a vessel. Both systems correct for pitch,roll,and yaw.
Free correction is available through NOAA, they collect info from CORS (Continuously Operating Reference Station). The RTK bases are both public and privately maintained, you would still need a L1/L2 capable receiver. CORS operates in most states. The nearest base for us is Natchez,Ms., it is maintained by the University of Southern Mississippi. I think CORS was established to create flood zone maps and to have a known reference for elevation in response to a natural disaster.
This should be the CORS RTK for Michigan
