At 13:40 Beijing time on September 21,a LM-4B carrier rocket lifted off from the Jiuquan Satellite Launch Center,and successfully launched the HY-2C satellite into orbit.

HY-2C,the second ocean dynamic detection series satellite that was constructed under the National Civil Space Infrastructure Plan,was developed by the China Academy of Space Technology,CASC.It can provide all-weather and round-theclock observation of wave height,sea surface height,wind and temperature.

The onboard automatic identification system (AIS) can identify global ships,and the distributed control system (DCS) can receive,store and transmit buoy measurement data in China’s offshore and other marine areas,effectively improving the data accuracy.

After the HY-2C forms a network with the previous HY-2B and subsequent HY-2D satellites,China will have the world’s first ocean dynamic environment observation network that can observe a series of dynamic environment elements on the global sea surface.It can provide information support for China’s marine disaster prevention and mitigation,meteorology,transportation and scientific applications,help build the global marine observation network,and improve the international status of China’s marine satellite system.

As a large maritime country,China’s Gross Ocean Product (GOP) in 2019reached 9% of GOP.The successful launch and networking of the HY-2 series of satellites will further improve China’s early warning capability of marine dynamic environment and bring many sustainable and predictable benefits.

The LM-4B carrier rocket was developed by the Shanghai Academy of Spaceflight Technology.The three-stage conventional liquid propellant rocket is capable of launching different satellites with different orbit requirements.

This was the 67th launch as well as the fourth mission in 2020 of the LM-4B series carrier rocket.

This was the 347th launch of the LM series launch vehicle.(REN Yueming/China Space News)
