AlphaAir 15
Pushing the Boundaries of UAV Sensing and Mapping
Built on cutting-edge LiDAR technology, the AA15 combines high-end CHCNav laser scanner, high-end multi-constellation GNSS/inertial sensors, and an add-on high-resolution RGB camera
- Long-range LiDAR scanning capability of up to 1800 m
- Highest data quality and point density, up to 2 million measurements per second, scan speed up to 600 lines per second, and field of view of 75°
- Supports several external camera accessories, including CHCNAV’s 45 or 61 MP full-frame calibrated cameras and a 130 MP oblique camera
- Flexible and easy installation on diverse platforms, including helicopters, small aircrafts, and various drones, including CHCNav X500
- Seamless data processing, feature extraction, and compatibility with other industry-standard tools
- Ideal for large-scale corridor mapping operations such as power lines, highways, railroads and pipeline inspections, and well suited for open-pit mining, urban mapping and forestry applications
