Description
Improving Never Stops
J1 is designed to enhance your performance in the field survey and to provide the most reliable positioning result.
It integrates a 1598 channels world leading GNSS positioning engine, high precision IMU, long range UHF radio and new interact operating system.
More features are to be discovered by you…
More channels and all constellations tracking
With 1598 GNSS channels solution, J1 can support multi-constellation and multifrequency tracking with the help of high-performance GNSS antenna.
More powerful inbuilt radio
Coupling a high-performance UHF module with Farlink communication technology,
which increases signal sensitivity and transmission efficiency, J1 really achieves the goal
of a 8~15km ultra-long-distance working range. And the power consumption of this
carrying new generation module is 60% lower than additional UHF, making the Base
working time is much longer.
Superior Endurance, Up to 25 hours working
J1 uses a built-in 10000mAh ultra-large capacity Li-ion battery, which can last 25
hours of continuous work (Static) benefits from low power consumption circuit design.
The Type-C interface is used on J1 that it can support fast charging through a charger
with PD protocol, and it can be full charged in 4 hours.
Double data backup
The measured data can be simultaneously stored into both internal memory of
receiver and controller, realizing the measured data double backup, which effectively
avoid data loss.
Outstanding IMU measurement
Built-in 4th-generation IMU automatic compensator corrects the coordinates to the
pole tip, assisting surveyors to quickly and accurately measure or stake out point at will
without strictly leveling the receiver, the tilt angle range can achieve up to 60°.
Upward and hidden UHF antenna design
Upward UHF antenna design, achieving all-direction UHF signal receiving and
transmitting. And the antenna interface is hidden into top cover that effectively avoid
accident breaking, protect from water and dust.
Intelligent base signal locking technology
Using one-to-one signal tracking and locking technology, and the independent
frequency under Farlink protocol, the J1 rover can continuously lock and capture the
target base station signal to reduce cross-frequency interference even though other
base stations are working nearby with the same channel.
Smart system management-ROS
J1 is integrated with the ROS system, which comes with intelligent deployment of
multi-mode hardware components, strong computing power and an intelligent
scheduling mechanism, and coupling with an ultra-fine memory management
mechanism, making the fluency and running speed of the receiver comprehensively
improved.
