Galaxy G7 GNSS receiver

The Galaxy G7 GNSS receiver provides the highest measurement accuracy and reliability, allowing the user to be confident in the quality of the data obtained. The receiver supports all GNSS system signals and frequencies. The G7 has a magnesium alloy housing, tough line design, more delicate surface decoration, stronger sense of technological design and high durability.

Innovative design

Single button boot design, one button evokes all RTK operations. The body screen adopts a translucent high-strength panel, which has a stronger visual sense of technology.

Barrier-Free Measurement

Built-in 6800mAh high-capacity battery, the battery life is more than 10 hours, one charge, meets all-day work. Fully charged within 5 hours.

IMU survey

Built-in IMU compensator, corrects the coordinates according to the tilt direction and angle of the centering rod automatically within 60°.

Higher accuracy and reliability!

The most powerful GNSS RTK engine with 1598 channels;
Improve work efficiency by 20%;
Double speaker design;
5 km work range;
Built-in transceiver integrated radio.

***The relative and absolute accuracy, reliability and initialization time of the measurements depend on factors such as the duration of observations, atmospheric conditions, signal reflection, etc. Characteristic values are mentioned for normal and good sets. The use of BeiDou and Galileo satellites will increase the accuracy of the measurements and the performance of the instruments.
