"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 National Satellite Ocean Application Center, at the World Ocean Science and Technology Forum sub-forum "Ocean Observation and Exploration Technology Forum."
my country’s marine 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.
At the forum, experts introduced the role played by my country's marine satellites. For example, the Ocean 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 and has successfully completed various mission requirements. . It 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 for typhoon monitoring 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 guarantee the typhoon forecast meeting during the flood season The supplier provided near real-time typhoon information.
