Electric Auto-Steering System
EAS301 Pro is an eSurvey new generation autosteering system, it brings handy driving experience and higher crop yield for agriculture vehicle operators and farm managers. Combined with GNSS+INS technology, EAS301 Pro could transfer farm work from fully manual driving to semi-automatic operation. It means high time efficiency and less operator fatigue. Based on the route planning algorithm, vehicles could go through the same paths every time to seed, spray and harvest with ±2.5cm accuracy, increasing crop yield and reducing chemical usage.

All-purpose System: Suitable for Various Types of Agricultural Machinery
Able to apply it to multiple types of agricultural machinery, including tractors, transplanters, sprayers, harvesters, etc., to make your farm work more effectively.

Easy Installation: No Need to Change Hydraulic Circuit
Quickly install it on or remove it from your agricultural machinery as fast as 15 minutes, allowing you to quickly remove it from one agricultural machinery and install it on another.

Smart ECU: Easy configuration and upgrade
EAS301 Pro's ECU is based on a Linux system, it allows users to view position status, set up working mode, and update firmware from the Web user interface with any smartphone, tablet, or PC.

High Control Accuracy with Ultra-low Speed
Enable ±2.5 cm control accuracy even when the vehicle speed is as low as 0.2km/h, and no longer need to worry about fine planting vegetables and fruit crops.

24-hour Uninterrupted Work
Continuously work even in the day with strong lights or at night. Free RTK aid function could maintain centimeter accuracy for 600 seconds when the EAS301 lost correction data.

Rich Optional Functions
A user could choose upgradable functions like 20Hz DB9 NEMA direct output, dual camera, and ISOBUS-VT.
