China News Service, Beijing, August 17 (Guo Chaokai, Yang Cheng) According to China Aerospace Science and Technology Corporation on the 17th, China will launch two ocean satellites in 2020 and 2021, a total of four.
The China Ocean series satellites were developed by China Aerospace Science and Technology Corporation. Space-based ocean remote sensing, as a high-tech marine observation technology, has been widely used in marine environmental resource surveys, marine disaster prevention and mitigation, marine economy, marine ecology, maritime security, and national defense construction.
"As of August this year, China has independently developed and launched seven marine satellites, and jointly developed and launched one with France; two will be launched in September and November; two will be launched next year; two projects have been approved; five projects are in preparation "This is the latest data disclosed by Jiang Xingwei, an academician of the Chinese Academy of Engineering and director of the China National Satellite Ocean Application Center, at the "Marine Observation and Exploration Technology Forum", a sub-forum of the World Ocean Science and Technology Forum.
Among the marine series satellites that have been launched, the Haiyang-2A satellite is China’s first marine dynamic environment detection satellite and China’s first remote sensing satellite integrating active and passive microwave remote sensors. It has been in orbit for 8 years. All mission requirements were successfully completed. The satellite is still in orbit, providing data for all users.
Compared with the Ocean-2A satellite, the Ocean-2B satellite successfully launched in 2018 has greatly improved its observation accuracy, data product types and application efficiency. Using Ocean-2 A/B satellites to monitor typhoons in the Northwest Pacific region, it can capture the typhoon process throughout the year, and extract quantitative information such as the location of the typhoon center point, the radius of the gale, and the maximum wind speed, so as to ensure the typhoon forecast meeting during the flood season The supplier provided near real-time typhoon information.
