Meridian M20L Laser GNSS RTK Receiver

The Meridian M20L Laser GNSS RTK Receiver combines high-precision GNSS positioning with laser measurement, IMU tilt compensation and camera-assisted field surveying. Its calibration-free inertial system allows the receiver to measure points while the survey pole is tilted, while the integrated green laser can be used to measure points that are difficult or unsafe to occupy directly.

With 1408 GNSS channels, multi-constellation tracking, internal radio and cellular connectivity, the M20L is designed for flexible RTK workflows in surveying, construction and engineering projects. RTKSurvey.com supplies the Meridian M20L as a laser-enabled GNSS RTK solution for professional field applications.
