Galaxy G5 4

More channels and all constellations tracking

With 1760 GNSS channels solution, Galaxy G5 can support multi-constellation and multi-frequency tracking with the help of high-performance GNSS antenna.

Color touch screen, makes workflow simpler

HD 1.3-inch color LCD touch screen with high brightness and low power consumption, which is convenient and efficient to complete touch settings, information browsing, function settings.

More powerful inbuilt radio

Coupling a high-performance UHF module with Farlink communication technology, which increases signal sensitivity and transmission efficiency, Galaxy G5 really achieves the goal of a 10~15km 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

Galaxy G5 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 G5 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 G5 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

Galaxy G5 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.
