Overview
The CHCNAV AlphaAir 6 Dual (AA6D) is an airborne LiDAR system with dual APS‑C imaging designed for aerial mapping over complex and highly variable terrain. It pairs a long‑range laser with 5th‑generation waveform processing, a high‑performance IMU and two 26 MP CMOS APS‑C sensors to deliver dense point clouds and high‑resolution imagery.

Key highlights

• Laser range up to 2,100 m (80 %) and 960 m (10 %)
• Recommended flight altitudes: 100–600 m AGL
• 5th‑generation RWP (Real Waveform Processing) for improved density and completeness
• Dual CMOS APS‑C cameras with ultra‑wide 110° FOV
• Open interfaces for integration on multirotors, fixed‑wing UAVs and manned aircraft

Main features

• Long‑range scanning with high‑performance IMU: up to 2,100 m; IMU drift stability ≈ 0.3°/h
• High point‑cloud density: up to 1,000,000 pts/s at 120 m AGL (~220 pts/m²); 200,000 pts/s at 400 m AGL (~13 pts/m²)
• Dual APS‑C imaging: two 26 MP CMOS sensors (6252 × 4168), 110° camera FOV, 16 mm focal length
• Lightweight design: mass 1.85 kg, optimized for endurance (example: ~40 min on CHCNAV X500; mission coverage up to ~15 km²)

Performance and benefits
The system integrates a long‑range laser and a 500 Hz IMU to provide stable positioning and high accuracy across varied terrain. Real‑time waveform processing and multiperiod algorithms enable high PRR point‑cloud delivery, improved vegetation penetration and greater data completeness for surveying and inspection tasks.

Typical applications

• Topographic surveying and land mapping
• Forest inventory and canopy mapping
• Road and highway surveys
• Powerline inspection
• Emergency response and situational mapping

Associated media resources
Images and videos available showing sensor views (front/side/rear), sample surveys (forest, mountain) and demonstrations (laser + IMU operation, waveform processing, lightweight design and endurance).
