Meridian M20L Green Laser GNSS RTK is an innovative solution that combines advanced laser technology IMU, and 4G integration. It is calibration-free, significantly boosting operational efficiency and laser measuring makes the rodless survey improve efficiency and reduce risk factors. The M20L green laser receiver provides a new way to work in challenging & impossible& dangerous scenarios with high accuracy, including riverine stake-out, bridge pile surveying, elevation surveying, municipal surveying, outdoor & indoor combination surveying, and power station surveying, ect.
Laser technology offers unparalleled advantages in precision positioning and makes surveying work rodless and Easier. Combining cutting-edge 100m range laser technology with full constellation GNSS, IMU, and 4G integration, delivers calibration-free accuracy, significantly enhancing work efficiency and reducing potential risks.
Equipped with laser & 120° calibration-free IMU technology in a small body, it complements the laser's outstanding performance, extend- ing the M20L's application range to locations that traditional RTK systems cannot reach, opening up new horizons for product applica- tions, enhancing customer satisfaction and boosting operational effi- ciency.
With 7.4V 7000mah and the quick-charge capability, sup- ports you in working more than 26hours and greatly saves your time.
