CHCNAV AlphaAir 6 (AA6) – For Long-Range Aerial LiDAR Mapping

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

Long Range – Efficient Aerial Mapping

The AA6 LiDAR system offers a measurement range of up to 2,100 meters and is typically suitable for flight altitudes of 100–600 meters. The long range and powerful laser enable rapid mapping of large areas, even in varied terrain with high relief.

• IMU bias stability 0.3°/h
• 25 MP / 100 MP camera
• 4/3" CMOS sensor
• GNSS support for all major satellite systems
• Positioning accuracy of less than 5 cm
• 512 GB storage
• Weight only 1.35 kg
• IP64 protection

Efficient LiDAR Scanning

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

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

Accurate Positioning for Demanding Flight Missions

The AA6's 500 Hz inertial navigation system and 0.3°/h bias stability support accurate trajectory determination and the creation of high-quality point clouds. The system is designed to perform efficiently even when mapping high-relief and challenging terrains.

The GNSS system supports all major satellite positioning systems, and the manufacturer states a positioning accuracy of less than 5 cm in both horizontal and vertical directions.

High-Resolution Imaging

The AA6 features a 4/3-inch CMOS sensor, enabling 25-megapixel or 100-megapixel imaging modes. The high-resolution image data complements the LiDAR point cloud, allowing for more precise 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 operation. On the CHCNAV X500 platform, the system allows for up to 50 minutes of flight time and covers an area of approximately 15 km² in a single mission, according to the manufacturer.

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

Suitable for Diverse Professional Use

The AA6 is suitable for:

• land surveying and aerial mapping
• topographic mapping
• forest mapping
• road and route mapping
• power line and infrastructure inspections
• mine and quarry mapping
• measurement of high-relief terrains
• 3D point cloud production
• documentation of large areas
• UAV-based LiDAR measurement projects
