UAS Lidar Systems

AlphaAir 2400

Premium Airborne Laser Scanner With 2 150M Range for High-Altitude Lidar Mapping Over Large Areas

The AA2400 system integrates a Riegl’s VUX- 240 laser scanner and the industrial-grade CHCNAV’s GNSS & high precision IMU making it possible to provide up to 2 cm accuracy, depending on the scanning range. The AlphaAir 2400 is an airborne laser scanner offering an impressive combination of low weight, extended range, high accuracy, and scanning speed for missions at up to 1400 m operating flight altitude. The AA2400 can be easily installed on helicopters or airplanes and various UAVs.

Description

DATA ACQUISITION AT HIGH ALTITUDE

High-end GNSS + INS combined with Riegl VUX-240

The AlphaAir2400, with the extended scanning range, allows higher altitude missions of up to 1400 m to survey large areas and avoid potential collisions with high objects. The acquisition time is significantly reduced, especially for large corridor mapping projects from helicopters or aircraft. With its integrated VUX-240, the AA2400 features a wide 75-degree field of view and a high-speed data acquisition rate of up to 1.8 MHz with a scanning range of up to 2150 m at 80% albedo delivering 2 cm linear accuracy.

PROFESSIONAL IMAGING SENSORS

AA2400 can control up to four external cameras

Up to four cameras in nadir or nadir and oblique view with a high resolution of 100-150 MP, such as a PhaseOne camera, can be added to the AA2400. By obtaining high-resolution geo-referenced and/or oblique imagery, more applications can be supported, increasing the return on investment for the client.

EXTREME PRODUCTIVITY AND DATA QUALITY

The fast data acquisition rate of up to 1.8 MHz with up to 400 lines per second

The built-in VUX-240 LiDAR delivers 2 cm linear accuracy on long-range scans. The continuously rotating polygonal mirror wheel enables scan speeds of up to 400 lines per second, ideally suited for high-point density corridor mapping applications. The over-density of accurate data makes the results of point cloud processing, such as drawings, 3D models, or DTMs, more accurate.

The AlphaAir 2400 is an airborne laser scanner offering an impressive combination of low weight, extended range, high accuracy, and scanning speed for missions up to 1400 m operating flight altitude. The AA2400 can be easily installed on helicopters or aeroplanes and on various UAVs, such as CHCNAV's BB4.

The AA2400 system integrates a Riegl’s VUX- 240 laser scanner with a unique forward and backwards-looking FOV designed to minimize laser shadowing and provide geometry of complex vertical structures in a single pass. In addition, the VUX-240 airborne laser scanner features a wide 75-degree field of view and a high-speed data acquisition rate of up to 1.8 MHz and a scanning range of up to 2150 meters. The industrial-grade CHCNAV’s GNSS and high-precision IMU allow the AlphaAir 2400 to provide up to 2 cm accuracy, depending on the scanning range.
