SOUTH GALAXY 3
Behind every significant change in human society there is always the birth of an important technology. At the dawn of a new era, South is leading an era of high-precision positioning.
Color LED indicators
Longer battery life
Super radio and Farlink protocol
IMU for slope survey
Using multi-layer structure and high integration design, the Galaxy G3 receiver is very small, with dimensions 130mm X 80mm. Built with magnesium alloy materials, the weight is only 790g including internal battery, very light and convenient to carry.
The excellent performance of the Galaxy G3 allows you to understand high-tech in the surveying and mapping industry.
Independent indicators with different colors make the receiver’s working status and information clearer and more intuitive, and the function module can be clearly known even in bright light.
POWERFUL GNSS UNIT
G3’s GNSS card is integrated with an advanced SoC, a chip that features high integration and low power consumption, effectively suppresses interfering signals, and obtains higher quality observation data from satellite constellations
The GNSS board fits perfectly on the power board and is not removable.
High management and control capacity
The G3 is integrated with the ROS system, which comes with the intelligent implementation of multi-mode hardware components, strong computing power and intelligent scheduling mechanism, together with the ultra-thin memory management mechanism, make the receiver’s fluency and operating speed understandably improved.
It adopts the new “RTK engine algorithm” that optimizes data robustness, avoids the false point during survey, and ensures the reliability and stability of the coordinate result in complex environments.
Based on the signal tracking capability of the L-band, the Galaxy G3 can capture the precise orbit information and precise satellite clock error carried by the BeiDou-3 GEO satellite’s B2b signal, which can provide users with single-point positioning services at the centimeter level in real time through an accurate algorithm. The positioning is no longer restricted by the terrestrial environment, such as mountain, desert and island. The fixed solution is generally available as long as the GNSS constellations are visible.
Excellent performance and reliable algorithm technology help surveyors increase productivity.
Equipped with a super UHF module developed by SOUTH – “Beaver”, comes with 2W transmission power, the Galaxy G3 really achieves the goal of long distance work using a new radio-Farlink communication protocol, which increases signal sensitivity and transmission efficiency.
The frequency of each channel under the “Farlink” protocol is different from the commonly used ones, which effectively prevent interference from other radio signals.
