    Why choose a NAV III Controller?

    When installing Trimble Autopilot to your machine(s) with the compatible displays, the NAV III controller is one of the key elements in providing accurate machine information to control the steering valve amongst other elements. Superseding the NAV II controller, the NAV III has built in gyroscopes to compensate for vehicle roll, pitch and yaw across undulating ground. The controller also supplies multiple data inputs/ outputs which can be used for third party controllers or additional operations accordingly. Available with a wide range of brackets and cabling choices, the controller can be specified for a wide range of vehicle types and be compatible with the surroundings for a successful installation. Also used for implement steering, external NAV III enclosures are available for the controller when use in an outdoor environment.
