We will enhance our emergency remote sensing monitoring capabilities and successfully launch the High Orbit SAR satellite for emergency disaster reduction
At 1:26 on August 13th, China used the Long March-3B carrier rocket to launch the emergency disaster reduction high-orbit SAR satellite into its designated orbit at the Xichang Satellite Launch Center, achieving a successful launch mission.
The Emergency Management Department is the leading user department of the Emergency Disaster Reduction High Orbit SAR Satellite. The satellite is a research satellite and the world's first high orbit SAR satellite. It is equipped with L-band synthetic aperture radar and has medium spatial resolution, fast revisit observation, and large-scale coverage observation capabilities. It mainly provides data support for emergency management, natural resources, ecological environment, water conservancy, meteorology, agriculture and rural areas, forestry and grassland, earthquakes and other industries.
After the emergency disaster reduction high orbit SAR satellite is in orbit, the revisit period for the southeastern coastal areas of China is less than 4 hours, and the revisit period for the middle and lower reaches of the Yangtze River, the eastern part of the southwest region, the northern part of the Beijing Tianjin Hebei region, and the southern part of the northeast is less than 8 hours. This can significantly improve the emergency response capability for natural disasters such as floods and enhance the large-scale and continuous dynamic monitoring capability of the affected areas.
