Precision Steering System
EAS301 Pro is an auto-steering system that can adapt to different crops, regions and characteristics of agricultural equipment, relying on the advantages of the whole industry chain in the field of satellite positioning. It not only greatly improves the operation efficiency of agricultural machinery by the centimeter-level accuracy of repeated farming operations and 24-hour uninterrupted work even in the day with strong lights or at night, but also reduces the labor intensity of drivers and increases the unit output.

EAS301 Pro has following features:

High control accuracy
Precisely complete your farm task owing to ±2.5 cm control accuracy, supported by our high positioning accuracy and high torque and high-speed electric steering wheel.

Atlas & aRTK technology
Do not need to set up any base stations to achieve centimeter accuracy, and work without interruption even when RTK corrections fail, based on our Atlas correction service.

Free from terrain worries
Do not need to worry about rough terrains, for roll and pitch of vehicle will be detected to ensure straight lines, supported by our terrain compensation technology.

NMEA message supported
Output messages GGA, GSV, VTG, GSA, ZDA, RMC and GST.

Rich optional accessories
- Angle sensor: it helps the vehicle to speed up to 0.1 – 18 km/h from 1 – 12 km/h.
- External IMU: it helps to improve the performance of auto-steering when you drive the vehicle in too steep and rough terrain at high speed.
- Rear camera: it helps to conveniently check the status of implements without turning round even at night, supported by its LED.
