BB4 UAV
Professional UAV Platform for Reality Capture
The BB4 is a high-performance quadcopter unmanned aerial system for professional imaging applications. It can carry the CHCNAV Lidar scanners with DSRL cameras for high-accuracy 3D point cloud generation or oblique cameras for 3D photogrammetry. With a setup time of only two minutes, the versatile BB4 offers up to 55 minutes of flight time with a 1 kg payload and up to 40 minutes with a 5 kg payload. The drone is controlled with the DJI Lightbridge 2 flight controller and a 5 km operating range.

Description
-
A STATE-OF-THE-ART MODERN PLATFORM
2 min for flight preparation
The BB4 UAV is specially designed for professional industrial applications. The modular design with pre-installed arms and antennas reduces the time required for setup, making the platform ready for use in just 2 minutes.
-
HIGH CAPACITY
Up to 7 kg payload
LiDAR weight is a constraint for any drone. The UAV needs to lift the entire payload; if not, no data acquisition is possible! The BB4 can carry our CHCNAV scanners with different DSRL cameras. 3D photogrammetry is possible with an oblique camera system. Users can also install multispectral cameras.
-
SURVEY-GRADE ACCURACY
1 cm +1 ppm RTK accuracy
The BB4 is equipped with dual DJI A3 IMUs and GNSS units that work together with CHCNAV's advanced positioning solution, consisting of a high-end GNSS receiver and an industry-leading IMU to meet the high accuracy requirements of the surveying and mapping industry.

INTELLIGENT AND FLIGHT-SIMPLIFIED OPERATION
BB4 operated by DJI Ground Station Pro
Enhance the BB4's operation with the DJI GS Pro application. Conduct automated flight missions, manage flight data in the cloud, and collaborate across projects to efficiently manage your drone workflow.
The BB4 is a high-end unmanned aircraft system resulting from an alliance between the two industry leaders in their respective segments. Its scientific design and highly integrated production technology come from CHCNAV - a global manufacturer specialising in efficient geospatial measurement technologies - and its fully automated flight control system from DJI, the pioneer in commercial UAVs.
