China's domestically produced Caihong, or Rainbow drone, will be used for exploration of geological resources in the Qinghai-Xizang Plateau and polar regions, according to a statement released by the Aerospace CH UAV Co on Wednesday.

Aerospace CH UAV Co is a listed company under China Aerospace Science and Technology Corp.

The China Aero Geophysical Survey and Remote Sensing Center for Natural Resources and Aerospace CH UAV Co signed a framework agreement on strategic cooperation on March 17 to establish a comprehensive strategic partnership in several fields, including Aerogeophysical exploration tech research and development of drones, and technical services at home and abroad.

Aerogeophysical exploration is a new and high-tech method that combines geophysical exploration and aviation and can obtain a variety of geophysical field information quickly and efficiently. There are advantages for drones to carry out the survey as they can work fast and efficiently and will not be affected by terrain conditions and human factors, the company said.

It has become a global technical trend to solve airborne geophysical surveys to combine the tech of drones and geophysical exploration, according to the company.
