CHCNAV AlphaAir 6 (AA6) – Long-range airborne LiDAR mapping

The CHCNAV AlphaAir 6 (AA6) is a powerful system designed for airborne LiDAR surveying, combining long-range laser scanning, high-precision inertial navigation, and high-resolution imaging. The AA6 is specifically designed for UAV-based mapping and demanding terrains where efficient and accurate 3D data collection is required.

Long range – efficient airborne mapping

The AA6 LiDAR system has a measurement range of up to 2,100 meters, with typical flight altitudes between 100 and 600 meters. The long range and powerful laser allow for the rapid mapping of large areas, even in varied and high-relief terrain.

Key benefits

• LiDAR range up to 2,100 m
• Up to 2,000,000 laser pulses per second
• 90° field of view
• Up to 16 returns
• 500 Hz IMU
• IMU bias stability 0.3°/h
• 25 MP / 100 MP camera
• 4/3" CMOS sensor
• GNSS support for all major satellite systems
• Positioning accuracy down to less than 5 cm
• 512 GB storage
• Weight only 1.35 kg
• IP64 protection

Efficient LiDAR scanning

The AA6's next-generation laser system enables a pulse rate of up to 2,000,000 points per second. Fifth-generation real-time waveform processing improves point cloud density and data coverage.

The performance reported by CHCNAV reaches up to 2,000,000 points/s and approximately 460 points/m² at an altitude of 120 meters. At 400 meters, the system produces up to 300,000 points/s and approximately 20 points/m².

Precise positioning for demanding flight missions

The AA6's 500 Hz inertial navigation system and 0.3°/h bias stability support precise trajectory determination and the generation of high-quality point clouds. The system is designed to operate effectively even when mapping high-relief and challenging terrain.

The GNSS system supports all major satellite positioning systems, and the manufacturer-stated positioning accuracy is down to less than 5 cm in both horizontal and vertical directions.

High-resolution imaging

The AA6 features a 4/3-inch CMOS sensor, allowing for 25-megapixel or 100-megapixel capture. High-resolution imagery complements the LiDAR point cloud and enables more accurate documentation of targets and the production of photogrammetric data.

Lightweight design – more flight time

Weighing only 1.35 kg, the AA6 is designed for efficient UAV use. On the CHCNAV X500 platform, the system allows for up to 50 minutes of flight time and coverage of approximately 15 km² in a single mission.

The AA6's open interfaces allow for integration with other manufacturers' multi-rotor and fixed-wing UAV platforms, as well as manned aircraft.

Suitable for versatile professional use

The AA6 is suitable for, for example:

• land surveying and aerial mapping
• topographic mapping
• forest mapping
• road and infrastructure mapping
• inspections of power lines and infrastructure
• mining and quarry mapping
• measuring high-relief terrain
• 3D point cloud production
• documentation of large areas
• UAV-based LiDAR measurement projects
