The system includes a control tablet integrated with a high-precision GNSS board, a steering wheel motor with a built-in controller, and an angle sensor. It controls the vehicle and co-operates with a base station to form a whole machine control system for agriculture applications. It can be widely used for sowing, cultivating, trenching, ridging, spraying pesticide, transplanting, land consolidation, harvesting and other work scenarios.





GNSS Accessories AX3702 640x340px.png
The AX3702 is a mini survey antenna. It can receive GPS L1/L2, GLONASS L1/L2, and BeiDou B1/B2/B3 signals, which can be used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, agriculture applications, etc. The AX3702 was calibrated in NGS. Customers can use the antenna for GPS-only or three-constellation navigation applications.
