Not a farmer but a retired land surveyor with farmer friends.
Interested in UBLOX products and have experimented with Emlids M8T ,F9P and UBLOX C099-F9P modules. I have used Auscors sites and local survey observation pillars to check performance.
I have really appreciated the information found on the AGOPENGPS site for setting up my own base stations, rovers and moving base setups.
