TAIYUAN, China (China National Space Administration PR) — At 11:10 am on July 3, 2020, China successfully launched a Gaofen high-resolution, multi-mode integrated imaging satellite with the Long March 4B carrier rocket at the Taiyuan Satellite Launch Center. The mission also launched the “Xibaipo” youth science satellite.

Gaofen is a civilian optical remote sensing satellite with sub-meter resolution, which can switch multiple imaging modes. Its on-orbit application will further improve the technical level of remote sensing satellites in my country and meet the needs of user departments in related industries for high-precision remote sensing image data. 

The high-resolution multi-mode satellite is the optical remote-sensing satellite with the highest resolution in the National Medium- and Long-Term Development Plan for Civil Space Infrastructure (2015-2025). It was established in 2018 and adopted the government-social capital cooperation model (PPP) construction and implementation. 

The satellite uses a medium-sized agile remote sensing satellite public platform organized by the China National Space Administration, and runs in the solar synchronous orbit. The satellite is equipped with operational loads such as high-resolution cameras, atmospheric synchronous correctors, and laser communication terminal test loads. 

During on-orbit operation, the high-score multi-mode satellite will verify a number of technologies such as agile maneuvering control, agile imaging, and image processing, and realize the functions of image on-orbit cloud judgment and target extraction in specific areas. 

In the follow-up, the high-resolution multi-mode satellite will be widely used in dozens of businesses in many industries such as surveying and mapping, agriculture, environmental protection, forestry, etc., to further meet natural resources, survey monitoring, development and utilization, geological survey, emergency disaster reduction, agricultural survey, housing construction, etc. High-precision data needs in monitoring, forestry protection and other fields.

In addition, the mission also carried the “Xibaipo” youth science satellite, mainly used for youth space science education promotion. The satellite is mainly equipped with programmable educational load, remote sensing camera load and sky-ground comparison experimental load, which can realize the function of comparing ground image data with satellite remote sensing data and physical experiment data.

This launch is the 337th launch of the Long March series of launch vehicles.

The China National Space Administration is responsible for the implementation and management of engineering organizations, and the Ministry of Natural Resources and other user departments are responsible for the construction and application of application systems.

The development of satellite systems is the responsibility of the general manager of China Academy of Space Technology, a subsidiary of China Aerospace Science and Technology Corporation.

The launch site and the measurement and control system are organized by the China Satellite Launch Measurement and Control System Department.

The China Land Observation Satellite Data Center is responsible for the construction and operation of the ground system.
