AlphaUni 300


AlphaUni 300/900/1300, belonging to our Alpha Mobile Mapping series, are high-end multi-platform LiDAR systems that have been designed and improved by CHCNAV based on many years of research and data capture experience. AlphaUni series is a fully integrated system with a high-precision laser scanner featuring Riegl’s unique Waveform-LiDAR technology and a high-accuracy inertial navigation system, ready for demanding surveying missions in the air and on the ground, requiring the highest data quality. The AlphaUni series fulfils our goal to provide the most innovative solutions to professionals in the geospatial sector and help them to save time, reduce costs and complete their projects more easily.



2.1 kg total weight
LiDAR weight is a constraint for any drone. The drone needs to lift the entire payload, if not, no data acquisition is possible! The lighter the unit, the higher the productivity, because your UAV can fly longer.


Integrated premium scanners
Users can select either the miniVUX-1 or miniVUX-2 UAV for higher data density. Equipped with industry-leading GNSS and IMU sensors, the AlphaUni300 provides the best combination of point cloud density, precision and survey-grade accuracy.


Support multiple platforms installation
Within 5 minutes, the AlphaUni 300 can be mounted on various platforms, including different models of UAVs, fixed-wing and multi-rotor VTOLs UAS, vehicles, backpacks, USVs and boats, enabling data collection in the most challenging environments.


Long range UHF modem onboard
Equipped with a unique 8 km UHF data transmission, the parameters of AlphaUni 300 can be set remotely. The operating status of the system can be observed wirelessly in real time, reducing mission preparation time and improving operational efficiency.


Powerful and accurate 3D point cloud generation
CoPre is an advanced, user-friendly 3D laser scanning pre-processing software that can process captured raw data, including POS trajectories, LiDAR data, and RGB images. CoProcess is a reality capture post-processing software providing DEM/DTM generation, semi-automated feature extraction, automatic data classification, and dedicated power line and road inspection modules.  With its intuitive interface and efficient workflow, the software significantly improves the productivity of 3D mapping projects.
