Since 2019, the company has accumulated about 300,000 km of actual flight experience with a daily regular cruise mileage of about 300 km, and has cultivated and trained an experienced and skilled flight team. Meanwhile, the company has independently designed and developed the "Bird The "Bird" series of netlink/radio dual-mode UAVs have solved the pain points of poor signal bypassing ability and the control and image transmission distance of only 10 km or so, which have achieved good application in the field of 100 km-level normal inspection such as river inspection, coastline inspection, highway inspection, long-distance pipeline inspection of natural gas and refined oil products. At the same time, it can switch to radio mode when the network communication base station is paralyzed in a large area, and the image and data transmission distance can still be as high as 60km, which solves the problem of over-the-horizon emergency rescue and material delivery difficulties of the net-linked UAV in extreme situations. The dual backup function of network communication system and radio communication system perfectly compensates for the limitations of each system, thus greatly increasing the environmental adaptability and reliability of the whole flight system.
