Meridian M27LV

Laser&Photogrammetry GNSS Receiver

The Meridian M27LV seamlessly combines high-precision laser measurement with an integrated high resolution camera, enabling a powerful Laser-Visual Fusion workflow. In complex field condi tions-such as bright sunlight, reflective surfaces, or long-distance targets-the camera functions as the system’s eye, delivering real-time visual feedback for accurate and confident targeting.

AR Stakeout

Visual positioning eases point finding by overlaying design files onto real scenes, enhancing stakeout efficiency,A high-performance HD camera achieves high accuracy with precise signal tracking. The 360-de-gree AR stakeout seamlessly switches between the handheld controller and rover, ensuring fast and accu-rate stakeout experiences

Calibration-Free Solution

Equipped with laser & 120° calibration-free IMU techno lo-gy in a small body, it complements the laser’s outstanding performance, extending the M27LV applica tion range to locations that traditional RTK systems cannot reach, open-ing up new horizons for product applications, enhancing customer satisfaction and boosting operational efficiency

Longer Working Distance

Equipped the MeridianLink protocol internal radio offers 15km working range and increases flexibility. By eliminat ing the need for an external radio, the M27LV becomes more lightweight, less complex, and more portable, which can lead to increased efficiency and convenience in the field
