G7 adopts a new design for the case, and with a high strength translucent control panel, it makes the operation process and instrument status display more intuitive.



Satellite tracking status indication

Data interaction


Single button start design

Small format

Using multi-layer structure and high integration design, it makes the Galaxy G7 receiver very small.

Dimension:: 135mm(L)×135mm(W)×84.75mm(H)

Built with magnesium alloy materials, the weight is only 970g, including internal battery. Extremely light and convenient to carry.

Fully supports tracking of all signals

Galaxy G7 is equipped with an integrated high and low frequency antenna, using low profile design technology to reduce the physical difference between the high and low bands. The applied frequency selective radiation mechanism would improve the anti-interference capability of the antenna. Combined with the powerful GNSS RTK engine with 965 channels, this Galaxy G7 fully supports all satellite constellations in operation, especially BeiDou III global satellite signals.

Excellent IMU tilt measurement

Galaxy G7 is integrated with a new generation IMU module that makes slope measurement more stable and accurate, coordinates would be corrected automatically according to slope direction and pole angle, which helps you to measure or survey points at will quickly and accurately without strictly leveling the receiver, helps surveyors increase productivity by 30%.

Barrier-free measurement
The new generation platform provides RTK with more stable performance and lower power consumption. The integrated high performance 6800mAh battery can support over 10 hours of continuous operation, without worrying about working all day.

Incredible UHF communication

Equipped with a new self-developed UHF module from SOUTH, the G7 truly achieves the goal of long-distance working using a new radio-Farlink communication protocol, which increases signal sensitivity and transmission efficiency.

  • Improves special signal recognition
  • Increased transmission bandwidth
  • Accommodates large volumes of data
  • Interference suppression
  • Low energy consumption
  • Typically 5km working range

Multi-path for communication

  • Bluetooth module 4.0: Greatly improves connection speed and data transmission capacity.
  • NFC: Makes the Bluetooth connection faster by connecting the controller to the NFC tag.
  • WiFi: For access to the internal web interface, or connection to the Internet for correction of the data stream, while communicating with the controller.
  • 7-pin USB: Data transmission and access to the web interface.
  • 5-pin LEMO: External power supply and RS232 interface.
  • UHF antenna interface: Improves the UHF signal.
