China News Service, Beijing, September 27th (Guo Chaokai) At 11:23 on September 27th, Beijing time, China successfully launched the Environmental Disaster Mitigation-2A at the Taiyuan Satellite Launch Center using the Long March 4B carrier rocket with one arrow and two stars. , B satellite.
This group of satellites will replace the Environmental Disaster Mitigation One A and B satellites that are in orbit overtime. They can be used to support emergency management business applications, and serve a wide range of environmental protection, natural resources, water conservancy, agriculture, forestry, earthquake and other application users to further satisfy The country's demand for continuous data supply in related fields
Environmental Disaster Reduction II A and B satellites are two 16-meter optical satellites planned in China’s "National Civil Space Infrastructure Medium and Long-term Development Plan (2015-2025)". The satellites use the CAST2000 platform, which has high mobility, high precision control, High stability, strong load adaptability and long life.
Both satellites are equipped with 4 types of payloads, including 16-meter cameras, hyperspectral imagers, infrared cameras and atmospheric correction devices, and can provide 16-meter multi-spectral, 48-meter hyper-spectral and 48-meter infrared image data.
After the launch, the satellite will focus on disaster prevention and mitigation, and environmental protection as its main business. It can provide strong support for natural disaster element monitoring, land use macro-monitoring, water resources supervision and protection, crop area dynamic monitoring and yield evaluation, and earthquake emergency rescue.
It is understood that the A and B satellites that were replaced this time were launched on September 6, 2008 and have been in orbit for nearly 12 years.
During its orbit, the satellite obtained a large amount of remote sensing data such as multispectral, hyperspectral, and infrared, and provided a large number of images and data to relevant units in response to major natural disasters such as the Wenchuan earthquake, the Yushu earthquake in Qinghai, and the Zhouqu torrential mudslide. The data provides an important basis for disaster relief activities.
This mission is the 348th flight of the Long March series of carrier rockets.
The China National Space Administration is responsible for the organization, implementation and management of the Environmental Disaster Reduction II A and B satellite projects, with the Chinese Ministry of Emergency Management and the Chinese Ministry of Ecology and Environment as the lead user departments.
The China Academy of Space Technology and Shanghai Academy of Aerospace Technology subordinate to China Aerospace Science and Technology Corporation are responsible for the development of satellite systems and launch vehicle systems.
