Xinhua News Agency, Beijing, September 21 (Reporter Hu Zhe) On September 21, the Ocean II C satellite was successfully launched into space. This is the second satellite in China’s dynamic marine environment monitoring network, and also China’s first large-scale remote sensing satellite operating in an inclined orbit. Once in orbit, it will network with the Ocean 2B satellite, greatly increasing the range and efficiency of China’s ocean observation. And observation precision.
The Ocean-2 C satellite is the second operational satellite in the Ocean Power series of satellites in the national civil space infrastructure. The National Space Administration is responsible for the organization and management of the Ocean-2 C satellite project. The Ministry of Natural Resources is the main users department and the Ministry of Natural Resources belongs to the national satellite. The Marine Applications Center is responsible for the construction and operation of ground systems and application systems.

Once the satellite is in orbit, it mainly makes high-precision and high-resolution real-time observations of sea height, effective wave height and sea surface wind field, and has the ability to identify ships and receive, store and send buoy measurement data off the coast of China and other sea areas. The designers kindly summarized its functions as “catching the wind, surveying the sea, examining ships, collecting records.”
Among them, the ship identification system can perform calculations of the ship’s position, course and speed on the global sea surface, as well as other data calculations, greatly enhancing maritime traffic and maritime safety capabilities; The data collection system can effectively obtain marine buoy signal data and uniformly transmit the buoy point measurement information to the ground. By processing, the precision of the marine forecast system is greatly improved through the precise measurement of the point and surface combination.

According to the person in charge of the satellite development team of the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the Ocean-2C satellite has the characteristics of agility, quick eyes and quick hands, and can achieve a higher frequency of observation of the ocean wind. Compared to the synchronous orbit of the sun in which traditional remote sensing satellites operate, the Ocean-2 C satellite “station” is very unique. Under the careful design of the development team, the C satellite will “run at full force” in an inclined orbit, further enhancing China’s ocean observing capabilities.
The Ocean II C satellite will operate together with the Ocean II B satellite launched in October 2018 and subsequent inclined orbit satellites to form China’s first dynamic marine environment monitoring network, which can complete 80% of the sea surface. of the world in 6 hours. Monitoring of wind farms. Compared to Ocean-2A and Ocean-2B, this satellite has improved the ability to quickly revisit the wind field on the sea surface.

In addition, Ocean-2C has realized the optimization of the launch site process of large remote sensing satellites by transporting the solar wing of the belt of the whole satellite, which greatly shortens the duty cycle of the launch site, and has a good promotion and optimization for the subsequent optimization of the process of large remote sensing satellites and commercial satellites. Demonstration effect.
