On May 9, 2018, Long March-4C rocket successfully put the first high spectral resolution observation satellite (No.5), which was developed by the Shanghai Academy of Spaceflight Technology, into the scheduled orbit.

High spectral resolution (No.5) satellite is the first observation satellite in China, and the only high spectral observation satellite. It is one of the important symbols for our country to be able to observe the earth with high spectral resolution.

High spectral resolution (No.5) satellite represents the technical frontier of the international high spectral optical remote sensing satellite and is equipped with 6 newly developed payloads, including 2 advanced hyperspectral / multispectral land observation payloads and 4 advanced atmospheric observation payloads. The satellite has the characteristics of wide spectral range, high spectral resolution, various detection methods, high calibration precision, high reliability and long life design. Six payloads have realized the hyperspectral observation of the full spectral range from ultraviolet to long wave infrared. The spectral resolution of the satellite is the highest in the country, and atmospheric and ground features of the "fingerprint" spectral information of can be obtained.

The main mission of the high spectral resolution (No.5) satellite is to monitor the ecological environment of inland water bodies and land surfaces, to monitor atmospheric components such as carbon dioxide, methane, ozone, nitrogen dioxide, sulfur dioxide and atmospheric aerosol characteristics, and to survey typical altered minerals and major rock types in geological prospecting. When put into use, it will provide strong support for China's comprehensive environmental monitoring, land and resources exploration, climate change research, disaster prevention and mitigation, crop classification and yield estimation, and play an important exemplary role in the application of hyperspectral remote sensing satellites. As such, it is crucial to the building of a beautiful China.
