The inauguration ceremony of the joint research center for global change space-based observation system and the satellite remote sensing Summit Forum jointly established by Sun Yat sen University and China Academy of space technology was held at Sun Yat sen University on March 3. The reporter learned that Sun Yat sen University and China Academy of space technology will jointly develop and launch a polar satellite, which will be China's first scientific test satellite for Arctic channel monitoring, and is expected to be launched in 2022. At present, the design of satellite platform and payload has been basically completed.

According to Cheng Xiao, Dean of the school of Surveying and Mapping Science and technology of Sun Yat sen University, China's first synthetic aperture (SAR) for Arctic channel monitoring was launched by the joint research center of global change space-based observation system Radar is an X-band synthetic aperture radar satellite with full polarization mode. It operates in the sun synchronous orbit at the height of 720 km. It can realize the repeated observation every two days in most areas of the Arctic.

Cheng Xiao said that in the process of observing global environmental change, Arctic sea ice is an important measurement index. Global warming, haze and other issues are closely related to the reduction of Arctic sea ice. However, it is difficult for the world to accurately predict the current situation and future trend of Arctic sea ice.

It is reported that the polar satellite is designed by Sun Yat-sen University, which can monitor global climate change and Arctic ice melting in real time and realize global data sharing. "The satellite has global observation capabilities, but we focus on Arctic sea ice changes ." Cheng said ," compared with other similar international satellites, the satellite can be a large part of the Arctic region within 24 hours to re-visit, the accuracy and frequency of observation will be better than the existing polar satellite level ."

On the same day, the Joint Research Center for Space-based Observing Systems for Global Change was inaugurated at Sun Yat-sen University. The Centre aims to demonstrate, research and develop original payloads in the light of major national needs and scientific objectives. It will jointly promote the establishment of innovative flux satellites, ice satellites and other global change satellite series projects, acquire original scientific observation data of independent intellectual property rights, and strive to produce a number of major scientific and technological achievements with international influence.
