Samsung Gathers China's First Marine Surveillance Monitoring Radar Satellite Constellation Officially Completed

[ Hot Focus on Chemical Machinery Equipment Network ] According to the National Space Administration, at 7:47 on April 7, 2022, China successfully launched a 1-meter C-SAR operational satellite with the Long March 4 Bingyao 38 carrier rocket at the Jiuquan Satellite Launch Center.

.
The satellite is the second C-band multi-polarization synthetic aperture radar service satellite in China.
It can realize the three-dimensional network operation with the first 1-meter C-SAR service satellite in orbit and the Gaofen-3 scientific experiment satellite, forming a land-sea network.
The radar satellite constellation, achieving 1-meter resolution and 1-day revisiting, will improve the sea and land observation capabilities of China's radar satellites, which can meet the needs of marine rights maintenance, marine disaster prevention and mitigation, marine dynamic environment monitoring, marine scientific research and disaster reduction, land, environmental protection, Application requirements in the fields of water conservancy, agriculture and meteorology
.

 

The Gaofen-3 satellite is a remote sensing satellite of China's Gaofen Special Project.
It is a radar remote sensing satellite with a resolution of 1 meter, and it is also China's first C-band multi-polarization synthetic aperture radar (SAR) imaging satellite with a resolution of 1 meter
.
The Gaofen-3 satellite has 12 imaging modes, covering traditional strip imaging mode and scanning imaging mode, as well as wave imaging mode and global observation imaging mode for ocean applications.
It is the synthetic aperture radar satellite with the most imaging modes in the world
.
The satellite imaging has a large width, combined with the advantages of high spatial resolution, it can not only achieve a large-scale census, but also a detailed survey of specific areas
 

　　After three satellites complete the network, compared with a single satellite, the average revisit time is increased from 15 hours to 5 hours
.
It can provide high-efficiency, stable, quantitative remote sensing data for operational applications for multi-element observations such as marine environment monitoring and marine target monitoring, emergency monitoring of natural disasters and safety production accidents, land use, and surface water bodies
.

 

　　The National Satellite Marine Application Center of the Ministry of Natural Resources said that in the future, it will conduct in-orbit testing of two satellites with relevant units, fully ensure that the satellites are put into use on time, realize the operation of multi-satellite networking services, and effectively meet the requirements of ocean, land, emergency, ecological Environmental protection, water conservancy, agriculture, meteorology and other fields of application needs
