AGI-4 Modular GNSS Receiver

On Track to Productivity

The first truly modular ISO-compliant steering system.


AGI-4 Receiver/Steering Controller

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 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.

Accuracy upgrades
Upgrade options for RTK include 900 mHz radio and US GSM, UHF Digital Modem with US GSM, and OmniSTAR HP/XP upgrade. Compatible with Topcon base stations, TopNet, GSM and CORS networks.

Plays well with others
AGI-4 features industry-leading ISO11783 compatibility with virtual terminals. This feature allows you to add Topcon’s industry-leading autosteering performance to many steer-ready vehicles via a single component installation. Compatible with many other manufacturer’s displays, the AGI-4 steering controller gives true Drop-in and Drive convenience.
