    All-in-one, modular design with antenna, receiver, and steering controller in a single component

    The AGI-4’s all-in-one, modular design incorporates the antenna, receiver and steering controller in a single component, offering unmatched upgradeability. AGI-4’s 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 options. Like all Topcon receivers, the AGI-4 offers GNSS multi-constellation satellite reception standard for unmatched accuracy in dynamic applications and terrain conditions.

    Expanded Connectivity for Superior Performance: NTRIP capability allows tapping into existing reference networks via cellular connection (dependent of local availability) and uses existing data plans and infrastructure to minimize costs.
    AGI-4’s ISO11783 compatibility with other virtual terminals (VT) provides drop-in and drive convenience.
