The AG501 Pro is ComNav's autosteer kit for precision agriculture, built around the A100 Pro smart antenna that combines a GNSS receiver, gyroscope and radio datalink in a single roof-mounted unit, paired with a steering-wheel actuator motor and an in-cab display terminal. It supports free correction sources such as Galileo-HAS and BeiDou-B2b alongside conventional RTK, giving pass-to-pass repeatability from roughly 2.5cm (with RTK) to 5-10cm (correction-free), and its GNSS+INS terrain compensation keeps guidance steady on sloped or uneven ground. Guidance patterns include straight and curved AB lines, A+ heading and automatic U-turns, and the kit is built for quick transfer between tractors, sprayers and harvesters.
