The base station should be placed at a point in the farm where there is fixed 230V power and wired internet (LAN/Ethernet cable), and the antenna should be placed on the roof (even glued to the roof tiles) so that it has a clear view of the sky. The base sends the correction over the internet to the Centipede server, which your tractor downloads in the field. We help remotely with the base registration and millimeter-accurate calibration (PPP)!
