The Extraordinary Inbuilt Radio

Galaxy G2 adopts a new self-developed digital radio module with "Farlink" protocol to achieve the typical working range as 8km. The transmission bandwidth of "Farlink” becomes large, which perfectly solves the problem of large data volume of multiple constellations transmission. And the power consumption can reduce about 60% in the same amount of data transmission compare to the traditional RTK.

Ultimate Goals of Full Signals Tracking

Galaxy G2 adopts high and low frequency integrated antenna design, which using low profile design technology to reduce the physical difference between high and low frequency bands, improves phase center consistency. And the applied frequency selective radiation mechanism would enhance antenna anti-interference ability. And combines with high performance GNSS board, G2 fully supports all of running satellite constellations, especially BeiDou III global satellite signals.

Worry-free Surveying

The new generation of SoC platform gives RTK more stable performance and lower power consumption. The built-in 6800mAh high-performance battery can support 15 hours* of continuous operation. G2 adopts Type-C charging interface which supports PD rapid charging, the battery can be full charged in 3 hours that supports full-day work.

Measure Whatever You Want

Galaxy G2 is integrated with a new generation Inertial Measurement Unit which makes tilt measurement more stable and accurate, the coordinates would be corrected automatically according to the inclination direction and angle of the pole, without strict leveling the receiver to measure the point at will, it helps surveyors boost productivity by 30 percent.
