G2Plus
High Precision Laser GNSS RTK
Overview
G2Plus Laser GNSS RTK is an innovative solution that combines advanced laser technology with Camera, IMU and 4G integration. It is calibration-free and significantly boosts operational efficiency.
Laser measuring makes roadless surveying more efficient and reduces risk factors in challenging scenarios including river-in stake-out, bridge pile surveying, elevation surveying, municipal surveying and outdoor/indoor combination surveying.
Key Features
Latest Laser Technology
Cutting-edge 100m laser technology with full constellation GNSS, IMU and 4G integration delivers calibration-free accuracy.
Calibration-Free Solution
Laser and 120° calibration-free IMU technology extend the G2Plus application range to locations traditional RTK systems cannot reach.
Longer Working Distance
Geo Pulse Link internal radio offers a 15km working range and removes the need for an external radio.
Full Constellations
Supports BDS, GPS, GLONASS, Galileo, QZSS and SBAS. Its 1408 channels provide comprehensive GNSS signal tracking.
