China News Service, Beijing, January 23 (by Ma Shuaisha and Zhang Wei) On January 23, the National Space Administration held a commissioning ceremony for the hyperspectral comprehensive observation satellite in Beijing.
The hyperspectral comprehensive observation satellite is an important component of China's major high-resolution earth observation system project.
In November 2023, the satellite completed the on-orbit test summary review. The satellite is in good condition, the functions of each subsystem are normal, the performance has reached various indicators stipulated in the general requirements for development and construction, and it is qualified for use.
It is understood that the satellite has the characteristics of hyperspectral, large-scale, quantitative detection, etc., and can achieve comprehensive detection of pollutant gases, inland water bodies, land surface ecological environment, altered minerals, rock and mineral categories and other elements, and can provide valuable information for China's ecological environment. It provides high-quality, highly reliable hyperspectral data for industrial applications such as natural resources, meteorology, etc., which can especially provide important data support for strengthening ecological environment protection and continuing to promote the battle against pollution.
At present, the satellite ground system has received a total of 245.2TB of data, produced 85,638 scenes of level 1 product data, and produced 19 categories of application-specific products.
During the satellite's in-orbit operation, user units carried out typical demonstration applications in the fields of natural resources, ecological environment, meteorology and other fields.
The satellite commissioning ceremony released the satellite's in-orbit delivery application products, including global ozone column concentration monitoring charts, global nitrogen dioxide column concentration monitoring charts, soil moisture monitoring charts, sea ice monitoring charts, soil heavy metal pollution level classification monitoring charts, and water quality monitoring. Hyperspectral data images such as this figure demonstrate the comprehensive observation capabilities and important application results of satellites in water pollution prevention and control, ecological environment supervision, mineral resource investigation, geological environment monitoring, dynamic monitoring of pollutant gases, and sea ice monitoring.
In addition, the satellite data will also be shared on the National Remote Sensing Data and Application Service Platform, which will continue to provide users at all levels with national civilian remote sensing data and product application services, including hyperspectral comprehensive observation satellite data, and promote the joint construction and sharing of China's remote sensing data. shared.
On the same day, Li Guoping, chief engineer of the National Space Administration, attended the ceremony.
Representatives from the Ministry of Ecology and Environment, the Ministry of Natural Resources, the China Meteorological Administration, China Aerospace Science and Technology Corporation and other units attended the ceremony and jointly signed the commissioning certificate for the hyperspectral comprehensive observation satellite.
It is reported that the National Space Administration is responsible for the organization and implementation of the hyperspectral comprehensive observation satellite project, and the Earth Observation and Data Center is responsible for the overall work of the satellite project.
The Ministry of Ecology and Environment, the Ministry of Natural Resources, the China Meteorological Administration and other departments are responsible for the construction and demonstration application of application systems.
The Shanghai Aerospace Technology Research Institute of China Aerospace Science and Technology Corporation is responsible for the development and production of satellites and launch vehicles.
Units such as the China Resources Satellite Application Center and the Institute of Aerospace Information Innovation of the Chinese Academy of Sciences are responsible for the construction and operation of ground systems.
