AG1 Guidance System
Practical GPS guidance for tractors and mixed-fleet farms
The FJD AG1 helps operators stay on planned paths without adding a full autosteering system. It uses RTK, PPP, and SBAS positioning, with accuracy from decimeter-level down to 2.5 cm with RTK. Start with the Standard system, then add ISOBUS or retrofit capabilities as your equipment needs grow.
Best for: Farmers who want affordable manual guidance and a path to ISOBUS control.

What the FJD AG1 does for you
Multiple Positioning Options
The AG1 works with RTK, PPP, and SBAS signals. Built-in algorithms provide sub-meter positioning in some signal-challenging areas, while RTK can provide accuracy up to 2.5 cm.
Manual Field Guidance
Use straight, curved, A+, pivot, and line-group guidance lines. The system also supports slope work, diagonal plowing, terraces, small fields, and hilly ground.
Wireless Installation
The GNSS receiver and display connect wirelessly through Wi-Fi. The basic setup uses a guidance terminal and GNSS receiver, which helps reduce wiring work.
Optional ISOBUS Control
The AG1 ISOBUS Kit adds VT, TC, and AUX functions for monitoring and controlling compatible implements from different brands through one terminal.
Sprayer Retrofit Option
The AG1 VCU Kit can retrofit a non-ISOBUS sprayer for use with ISOBUS systems. This adds automatic control and task execution without replacing the sprayer.
Field Data Connection
The AG1 can connect with FJDynamics FieldFusion to synchronize operational data and carry out planned tasks such as setting boundaries and guidance paths.

Common questions
Does the AG1 steer the tractor automatically?
The AG1 page describes manual guidance and path assistance. It does not state that the AG1 itself provides automatic steering. Call DST if you are looking for an autosteering setup.
Can I use the AG1 without RTK?
Yes. The system supports PPP and SBAS as well as RTK.5 cm accuracy.
Can the AG1 add ISOBUS to older equipment?
The AG1 ISOBUS Kit adds ISOBUS functionality, and the VCU Kit is designed to retrofit a non-ISOBUS sprayer. Call DST to check whether your specific equipment is supported.
