AT-B2
RTK Base Station
Built-in high-precision centimeter-level GNSS positioning module, ensure long-term use in precision agriculture, unmanned driving and other application fields.
Feature
High Precision
Provide reliable and effective calibration data for achieving centimeter-level positioning accuracy.
Correction
Adopt RTCM data format output. Reliable UHF data communication, compatible with a variety of UHF communication protocols, can be adapted to most of the radio mobile stations on the market.
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.
Reliability
With IP66&IP67 rating and UV protection, ensure high performance, accuracy and durability even in complicated and harsh environments.
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.
