Unistrong G20 GPS RTK Receiver

The Unistrong G20 is a multi-function GNSS RTK receiver combining satellite positioning, IMU tilt surveying, video measurement and AR-assisted stakeout. Its dual-camera configuration allows operators to extend point measurement into areas that may be difficult to occupy directly, while the 60° IMU system supports pole-tilt measurement during routine field work. RTKSurvey.com supplies the G20 for construction, engineering, topographic and earthwork surveying.
