G4 is equipped with every basic module like network, 2W radio, WiFi, IMU and extendable SSD (up to 128GB).
With all these modules installed, G4 is a utility player in the field. No matter what environments it encounters, neither for now nor in the future, G4 can always start to work with appropriate modules.
The yellow bodywork makes surveyors and the instrument more conspicuous. On the construction site, in the dense forest, others will easily notice the users of G4 and protect their safety.
Now surveyors can check the receiver's working status more clearly in complicated environments such as forests or at night. At the same time, it can be better seen from a long distance.
Here comes the Farlink 2.0. After years of hardware and firmware updates, Farlink 2.0 can undertake larger data and provide more stable transmission.
In addition, Farlink 2.0 can receive data from one specific base. Even though there are several bases transmitting with the same frequency, your rover will receive data from the correct base.
Each radio had extreme temperature-changing testing from 20ºC to 60ºC.
Unique SOUTH Algorithm,Reliable Working Power
SOUTH research team has a number of core technologies and unique algorithms, such as the SOUTH algorithm. It can correct data from harsh environments to obtain better accuracy.
Fixed-keep allows continuing to measure for a few minutes after losing the fixed solution.
Beidou PPP and Galileo HAS help you achieve precise point positioning through satellite broadcasted signals, so you can even work in areas without CORS corrections.
