If high precision farming is your business, you need the best possible guidance solution: AutoTrac and RTK (Real Time Kinematic)
Radio RTK works with a static local base station in or near your field, monitors the constellation of GPS satellites and continually calculates the position. It transmits corrections to the StarFire receiver on the RTK equipped vehicle.
Mobile RTK: In addition to the satellite GPS signal, mobile RTK correction data is sourced from a countrywide pool of existing base stations, so you don´t need your own. A centrally located server calculates the correction signal, which is then transmitted to the vehicle equipped with a John Deere Mobile RTK modem via the mobile phone network.
* Mobile RTK is an additional RTK technology available in selected countries
