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.
