Is Your Tractor Really Following the Right Path?

Traditional manual steering can make it difficult to maintain consistent routes during long hours of agricultural operations. Even small deviations may cause overlapping or missed areas during seeding, spraying and fertilization. Curved paths and uneven field conditions can further increase the difficulty of precise vehicle control. Operators also need to continuously adjust steering, which can increase workload and reduce overall efficiency. As precision agriculture develops, farmers need a more accurate and intelligent way to control agricultural vehicles while maintaining flexibility across different field conditions.

NG3A Makes Precision Steering Simpler

NG3A Auto Steering System combines high precision, intelligent control and simplified installation to address these challenges. With less than 2.5 cm working accuracy, NG3A supports both straight and curved driving paths, helping tractors follow predefined routes during precision farming operations. Its highly integrated design reduces the number of components required, enabling faster installation and easier maintenance. Intelligent algorithms and dynamic compensation improve steering performance on challenging terrain. The system can also be expanded for applications such as pesticide spraying, seeding and fertilization through additional hardware, providing a flexible solution for modern agricultural machinery.

Proven Positioning, Guidance and Autosteering​
What Can NG3A Auto Steering Do for Your Farm?
  • What modes does the NG3A support?

    RTK (Ntrip, Radio, Bluetooth), PPP (BDS B2b, Galileo E6‑HAS).
  • The device fails to acquire satellites.

    1. Check connections of the white GNSS antenna and its cable harness; 2. Power‑cycle and restart the system; 3. If satellite reception is still unavailable, replace the tablet, GNSS antenna or antenna cable as recommended.
  • What is the working accuracy under RTK mode, and what prerequisites are required to enable RTK mode?

    The working accuracy is 2.5 cm. At least one of the following two conditions shall be met: local NTRIP service, or a GNSS receiver with radio transmitting capability.
  • Is PPP service free of charge, and what is its accuracy?

    It is free, with an accuracy of 5‑10 cm.
  • Auto‑steering shows unavailable on the software.

    1. Tap Auto‑steering; the software will indicate the specific fault cause; 2. Verify all device cable harness connections are correct; 3. Confirm the positioning accuracy under RTK or PPP mode is better than 10 cm; 4. Check whether an work line has been created; 5. Contact technical support personnel.
