RTK Base Station with Built-in high-power UHF radio

AT-B2 is a professional base station with built-in high-precision centimeter-level GNSS positioning module, it can achieve 2.5cm accuracy, large-capacity battery and durable shell to ensure long-term use in outdoor environments. The carefully designed compact appearance makes it easy to carry. It is easy to operate and can quickly output high-precision differential data, which can be widely used in precision agriculture, excavators ,unmanned driving and other application fields.

Correction

Adopt RTCM data format output. Reliable UHF data communication, compatible with a variety of UHF communication protocols, SOUTH (9600bps), TRIMATLK (9600bps), TRANSEOT (9600bps), TRIMMARK3 (19200bps), can be adapted to most of the radio mobile stations on the market.

High Precision

Provide reliable and effective calibration data for achieving centimeter-level positioning accuracy.

Reliability

With IP66&IP67 rating and UV protection, ensure high performance, accuracy and durability even in complicated and harsh environments.

All-day Usage

Built-in 72Wh large-capacity Li-battery, supporting more than 20 hours of working time (typical), which is very suitable for long-term use.

User-friendliness

Battery level can be easily checked through the power indicator status by pressing the power button.

Wide-range Operation

Built-in high-power UHF radio, broadcasting distance over 5 kilometers, eliminating the need to move base stations frequently.
