Overview

About the A66MAX

Specifications

The A66MAX is a laser dual-camera RTK product, supporting BDS/GPS/GLONASS/Galileo/QZSS full-system, full-frequency high-precision positioning. It integrates visible laser, visual imaging, and IMU inertial modules, with the crosshair dynamically aligning the measuring spot for assisted aiming, combined with front and bottom HD cameras and IMU seamless inertial navigation, making measurement all-encompassing!

Dangerous Areas: In some hazardous areas, such as high-voltage towers or utility poles, laser measurements can avoid danger by measuring target points directly from a safe distance.

Cultural Relics: Pavilions, eaves, and other parts of cultural relics are not allowed to be approached; laser measurement can reach the measurement points directly, expanding the scope of measurements.

Bridge Piers and Bridges: Unreachable heights, such as bridge piers, bridges, or walls, can be precisely measured using laser combined with inertial navigation.

Multiplanar Intersection: Laser measurement supports multiplanar intersection measurement, which can further improve the accuracy of laser measurement points.
