UA301
Smart Positioning Antenna
UA301 has superior antenna gain, phase difference, quadrature axis ratio performance to obtain centimeter-level positioning accuracy. It can be used for agricultural, machinery assisted driving, engineering vehicles, ships, surveying and mapping and other fields.

- Multi-constellation and Multi-frequency
With 700 channels of GNSS tracking, UA301 provides stable and reliable accuracy. All GNSS signals are coming with standard including GPS, BDS, GLONASS, GALILEO and SBAS.

- L-band Atlas
Atlas is a service to provide global precision correction service over L-band satellites. With ATLAS subscription, UA301 is able to achieve centimeter accuracy without any base station.

- Wireless Communication
Build-in WIFI and Bluetooth models make it more convenient for remote control and data output.

- Web UI
It is able to view position status, set up working mode, download data and update firmware from Web user interface with any phone, tablet or PC.

- Rugged Design
UA301 main body is using aluminum alloy materials to provide strong shock and vibration resistant characteristics. IP67 certification ensures operation in various of tough environments.
