TAP Service

Tersus Advanced Positioning(TAP) provides global satellite-based Precise Point Positioning(PPP) service. TAP allows farmers to obtain high-precision positioning and navigation, without having to worry about network and radio base station anymore.

High Accuracy Steering

The AG993 supports L-band based TAP service and regular RTK. The AG993 can use multiple correction sources to deliver better than 2.5cm accuracy, which ensures autosteering accuracy and efficiency in various working modes and scenarios.

Integrated Connectivity

The GC30 Guidance Controller is highly integrated with Tersus anti-interference GNSS board, high precision IMU, 4G modem, WiFi, Bluetooth and internal radio. All-in-one solution provides quick and efficient device&cable installation.

User-Friendly Software

The TersusAG software provides clear interface, intuitive controls and friendly interactive operations. Simplify your display setup and help farmers easily control their autosteering vehicles.

Multiple Work Modes

Multiple guidance line & boundary types supported, to meet different working scenarios requirements.

Wide Compatibility

The hardware and control of the AG993 are compatible with over 90% agricultural vehicles of various brands.
