OUTSTANDING ACCURACY
The AU20 (or Alphauni 20) incorporates CHCNAV's high-precision navigation algorithm, the result of more than two decades of research. Combined with the scanner's remarkable 5 mm repeated ranging accuracy, the system achieves exceptional absolute accuracy of 2 to 5 cm, even in the most difficult and demanding environments.
EFFICIENT WORKFLOW
CHCNAV offers a complete solution for adding LiDAR surveying to users' geomatics services. Fully automated reality capture and real-time mission monitoring is provided by SmartGo software and intelligent point cloud processing by CoPre desktop software.
ENHANCED VEGETATION PENETRATION
With its advanced multi-target capability, the AU20 supports up to 16 target echoes for superior vegetation penetration ability. Capturing ground surfaces and generating accurate Digital Elevation Models (DEMs) and Digital Surface Models (DSMs) is made easy, even in difficult environments with dense vegetation.
LIGHT-WEIGHT
The AU20 LiDAR system is incredibly light and compact, weighing only 2.82 kg. Combined with the latest car mount kit, which includes a Ladybug5+, the total weight is only 10.7 kg.
MULTI-PLATFORM DESIGN
The AU20 follows CHCNAV's proven flexible multi-platform LiDAR design concept. It can be mounted on manned and unmanned aircraft for airborne scanning and on a variety of land vehicles such as cars, boats and trains for LIDAR mapping. It can also be conveniently mounted on a backpack for narrow area mapping.
