Helicopter-Borne Detection System Makes Strides in High-Altitude Terrain

China's Helicopter-Borne Geophysical Electromagnetic Detection System Makes Significant Strides

China has successfully conducted its first helicopter-borne geophysical electromagnetic detection mission in challenging high-altitude, frigid, and rugged terrain at 5,000 meters above sea level. This marks a significant advancement in supporting the planning and construction of key national railway infrastructure projects.

Developed by the Aerospace Information Research Institute of the Chinese Academy of Sciences, the system boasts full intellectual property rights and incorporates breakthroughs in high-sensitivity magnetic field sensors, large dynamic range signal reception, and a highly stable airborne pod platform. This enables the detection of underground faults, fractures, groundwater reserves, and mineral deposits, allowing for precise identification of areas with potential geological hazards.

Over a period of nearly two months, the research team conducted over 30 flights, mapping over 5,000 kilometers in harsh conditions marked by extreme cold and high altitudes. The system successfully reached a maximum detection depth exceeding 3,000 meters, providing crucial data support for the planning and execution of major national engineering projects.

Experts highlight the technology's ability to identify mineral resources, water reserves, and geological structures by analyzing variations in the electrical properties of underground materials. Its advantages include speed, high resolution, and wide coverage, making it a crucial asset in resource exploration and engineering assessment.

The system is particularly effective for underground detection in remote or inaccessible areas, such as plateaus, complex terrains, forests, deserts, gobi regions, and swamps. This supports the advancement of key national infrastructure projects, as reported by CCTV.
