Overview
The CHCNAV AlphaAir 6 Dual (AA6D) airborne LiDAR system is engineered for high‑resolution aerial surveying over complex and high‑relief terrain. It integrates prism‑based long‑range laser scanning, a high‑grade IMU and dual APS‑C CMOS cameras to provide extended ranging (up to 2,100 m), dense point clouds and ultra‑wide imagery. Open interfaces support multirotor and fixed‑wing UAV integration.

Main features

• Long‑range laser scanning: up to 2,100 m (80 %) and 960 m (10 %); scanner FOV 90°; up to 16 returns.
• High point throughput: scanner capacity up to 2,000,000 pts/s; typical operational densities up to 1,000,000 pts/s at 120 m AGL (~220 pts/m²).
• Dual APS‑C imaging: 26 MP × 2 (6252 × 4168), 110° FOV, 16 mm focal length.
• Lightweight design: 1.85 kg with field‑swappable storage and high data transfer capability.

Benefits and performances

• Extended range + high‑grade IMU: reliable measurements to 2,100 m and IMU bias stability ≈0.3°/h for accurate positioning in difficult terrain.
• Improved point cloud quality: 5th‑generation real‑time waveform processing (RWP) and multi‑period algorithms for better return separation and data completeness.
• Wide‑area imaging: dual APS‑C sensors (110° FOV) increase coverage and operational efficiency versus single‑camera systems.
• Operational readiness: compact 1.85 kg package, IP64 protection, operating −20 °C to +50 °C, internal 512 GB storage and fast offload.

Use cases

• Land and topographic surveying
• Forestry and canopy analysis
• Road and highway mapping
• Power line corridor inspection
• Emergency response and rapid mapping

Detailed description
The AA6D combines prism‑based long‑range laser technology, a 500 Hz high‑grade IMU and 5th‑generation RWP to deliver high‑density, high‑completeness point clouds at flight altitudes between 100 and 600 m AGL. Dual APS‑C cameras provide wide‑FOV, high‑resolution imagery synchronized with LiDAR data. Open interface protocols simplify integration across multirotor and fixed‑wing UAVs while the lightweight form factor and user‑swappable storage enable extended missions and rapid turnaround.
