Overview
The CHCNAV AlphaAir 6 (AA6) is an airborne LiDAR system combining long-range prism scanning, a high-grade IMU and switchable 100/25 MP imaging modes for efficient aerial surveying and mapping on UAV and manned platforms. Designed for complex, high-relief terrain, it supports typical operating altitudes of 100–600 m AGL and a maximum ranging capability up to 2,100 m.

Main features

• Long-range prism scanner with up to 2,100 m ranging capability (80%); typical AGL 100–600 m.
• High-grade IMU: bias stability ~0.3°/h, 500 Hz sampling for accurate inertial navigation.
• Point-cloud throughput: up to 1,000,000 pts/s at 120 m AGL (≈220 pts/m²) and 200,000 pts/s at 400 m AGL (≈13 pts/m²).
• Switchable imaging: 100 MP (12288 × 8192) or 25 MP (6144 × 4096) on a 4/3" CMOS, FOV 74°, focal length 12 mm.
• Ultra-light integrated design: weight 1.35 kg, enabling extended endurance and efficient coverage on UAV platforms (example: up to 50 min and ~15 km² per mission on CHCNAV X500).
• Open interfaces and integration support for multirotor UAVs, fixed-wing UAVs and manned aircraft.

Benefits and performances

• Reliable mapping in complex, high-relief terrain through combination of long-range laser and high-grade IMU.
• Real-time 5th-generation waveform (RWP) processing with multi-period capabilities to enhance point-cloud completeness and resolve multiple returns under high PRR.
• Flexible imaging modes to optimize GSD and signal sensitivity according to flight altitude and mission needs.
• Lightweight integrated package that extends flight endurance and increases area coverage per sortie on typical UAV platforms.
• 512 GB internal storage and high data throughput support large-volume acquisitions.

Use cases

• Topographic and aerial surveying in complex terrain
• Forest inventory and biomass assessments
• Road, highway and bridge mapping
• Power line corridor inspection
• Emergency response and rapid mapping
