Galaxy G9, IMU

The Galaxy G9 received a new processor that is not only energy efficient, but also copes well with interference, thanks to which it receives high-quality data from all constellations of satellites, including BeiDou III. Thanks to the innovative design and the latest technologies of the SOUTH company, work with VHF has become even more reliable. The built-in radio module of the new generation supports all modern radio protocols, operates at a frequency of 410-470 MHz, and the radius of operation is increased to 10 km thanks to the Farlink protocol. The Galaxy G9 comes with a new generation inertial system, which will make measurements at an angle more accurate. The coordinates will be automatically corrected for the angle and direction of the milestone. Thanks to this technology, the need to set a milestone by level disappears, and productivity increases by 30%.
