Agricultural autosteering retrofits tractors, sprayers, harvesters and other machines with GNSS, correction services, terrain compensation, steering control and an in-cab display. Accuracy depends on the complete system and correction availability, not the receiver alone.
Compare pass-to-pass accuracy together with correction method, convergence and outage behaviour. Confirm vehicle and hydraulic or electric steering compatibility, speed range, ISOBUS or CAN interfaces, display protection, communications, subscription cost, installation and local calibration support.
Use the table as a first comparison, not as a substitute for a technical agreement. Ask shortlisted manufacturers to confirm the current configuration, test method, duty cycle, charging or energy-supply boundary, applicable standards, warranty, local service and spare-parts plan in writing.
