The AlphaUni 20 is an advanced LiDAR solution designed to suit both aerial and ground mobile mapping applications. Providing an ideal balance of point cloud density, accuracy, and quality, it delivers absolute accuracy of 2 to 5 cm even in highly challenging environments, and features long-range scanning capabilities of up to 1450 metres.
The versatile LiDAR scanner's advanced multi-target capability supports up to 16 target returns for advanced vegetation penetration, making it ideal for high-accuracy Digital Elevation Model (DEM) and Digital Surface Model (DSM) generation. It can be easily fixed to a variety of UAV platforms, as well as ground vehicles and USVs.
The rugged unit is IP64-rated, ensuring high reliability in the field even under harsh weather conditions.
