A Long March-4B rocket, carrying the Haiyang-2C (HY-2C) satellite, is launched from the Jiuquan Satellite Launch Center in northwest China, Sept. 21, 2020. The country's third ocean dynamic environment satellite, the HY-2C, will form a network with the previous HY-2B and subsequent HY-2D to carry out high-precision maritime environment monitoring. (Photo by Wang Jiangbo/Xinhua)JIUQUAN, Sept. 21 (Xinhua) -- China on Monday sent a new ocean-monitoring satellite into orbit from the Jiuquan Satellite Launch Center in northwest China.
A Long March-4B rocket carrying the Haiyang-2C (HY-2C) satellite took off at 1:40 p.m. (Beijing Time), according to the launch center.
The HY-2C, the country's third ocean dynamic environment satellite, can provide all-weather and round-the-clock observation of wave height, sea surface height, wind and temperature.
Onboard equipment enables the new satellite to provide information on the identification of vessels, and to receive, store and transmit buoy measurement data in China's offshore and other marine areas.
Developed by the China Aerospace Science and Technology Corporation, the HY-2C will form a network with the previous HY-2B and subsequent HY-2D, scheduled for launch next year, to carry out high-precision maritime environment monitoring.
The planned satellite network will be capable of carrying out 80 percent of the world's sea surface wind monitoring within six hours, said sources with the China National Space Administration.
Unlike the previous satellites HY-2A and HY-2B -- the HY-2C will be placed in an orbit with a 66-degree inclination, which will enhance its capability to revisit wind fields rapidly, according to the administration.
As of August, China has independently developed and launched seven Haiyang satellites, named after the Chinese word for "ocean" and given the "HY" designation for short. The country launched its first ocean monitoring satellite, the HY-1A, on May 15, 2002.
In 2019, China's gross marine products accounted for 9 percent of its GDP. The follow-up network of HY-2 satellites will provide data support for marine disaster relief, meteorology, transportation and scientific applications, and help further enhance the country's marine monitoring capabilities, generating more sustainable, predictable benefits, the satellite developer said.
Monday's launch was the 347th by the Long March rocket series. Enditem

Built by the China Academy of Space Technology, a state-owned aerospace contractor, the Haiyang 2C satellite carries a radar altimeter and microwave scatterometer to measure the height of waves and monitor maritime wind field. The spacecraft also carries a payload to track ships and a data collection system to relay measurements from ocean buoys to forecast centers and other users.
China plans to launch its next oceanography satellite, Haiyang 2D, in 2021.
The Haiyang satellite series is named for the Chinese word for “ocean.”
China operates two families of Haiyang satellites — the Haiyang 1-series and Haiyang 2-series — that carry different sets of oceanography instruments. The latest member of the Haiyang 1 family, Haiyang 1D, launched in June with imaging sensors to measure ocean color, data which officials said will help track pollution and natural ocean constituents such as chlorophyll.
