2017 Topcon Agriculture AGI-4

The first truly modular ISO-compliant steering system.

The AGI-4's all-in-one, modular design incorporates the antenna, receiver and steering controller in a single component, offering unmatched upgradeability. AGI-4s steering system features state-of-the-art inertial sensors and full terrain compensation for superior line acquisition and holding capabilities.

The AGI-4 comes standard with WAAS and EGNOS, but is easily upgradeable to 2cm accuracy with RTK radio options. Like all Topcon receivers, the AGI-4 offers GNSS multi-constellation satellite reception standard for unmatched accuracy in dynamic applications and terrain conditions.
