At 13:40 on September 21, Beijing time, China successfully launched haiyang-2c satellite into the air by using the long march-4 yiyao-41 carrier rocket at Jiuquan Satellite Launch Center. The satellite entered the scheduled orbit successfully and the mission was a complete success. Haiyang-2c satellite is the second operational satellite of China’s national civil space infrastructure marine power satellite series. After the satellite is in orbit, it mainly realizes high-precision and high-resolution real-time observation of sea surface height, significant wave height and sea surface wind field, and has the ability of ship identification, receiving, storing and transmitting buoy survey data in China’s offshore and other sea areas. < p > < p > haiyang-2c satellite, together with the haiyang-2b satellite launched in October 2018 and the subsequent tilted orbit satellites, will jointly form the China marine dynamic environment monitoring network, which can complete 80% of the global sea surface wind field monitoring within 6 hours. Compared with haiyang-2a and haiyang-2b, the satellite operates in an inclined orbit of 66 degrees, which enhances the ability to quickly revisit the sea surface wind field. The National Space Administration of China is responsible for the organization, implementation and management of haiyang-2c satellite project. The Ministry of natural resources of China is the leading user department, and the national satellite marine application center of the Ministry of natural resources is responsible for the construction and operation of ground system and application system. China Academy of space technology and Shanghai Academy of aerospace technology, affiliated to China Aerospace Science and Technology Group Co., Ltd., are responsible for the development of satellite system and launch vehicle system; China satellite launch TT & C system department is responsible for the organization and implementation of launch site and TT & C system.
