[First in China! Drones Successfully Conduct Satellite Inspections in Signal-Free Areas] On July 14th, a breakthrough in power transmission line inspection technology was achieved in the remote mountains of Jianshui County, Honghe Prefecture, Yunnan Province. Drones autonomously inspected power transmission lines directly via satellite, without any 4G or 5G signals or ground-based differential positioning assistance. This operation, relying on a self-developed system, successfully established a direct signal channel between the ground station, satellite, and drone, overcoming the challenge of inspection in signal-free areas with practical accuracy. Project leader Li Bingchen explained that this technology breaks the previous limitation that inspection drones had to be connected via remote controllers to fly, enabling autonomous inspections even in signal-free areas. Approximately 4,500 kilometers of power transmission lines in Yunnan are located in mountainous areas without signal coverage. Using this technology, at least 90% of these areas can now be automatically inspected by drones. (CCTV News)
