HAIYANG 2D

Subject : Science & tech

Context : Recently, China has launched a Long March-4B rocket carrying the Haiyang-2D (HY-2D) satellite from the Jiuquan Satellite Launch Centre in northwest China.

Concept :

• China has independently developed and launched seven Haiyang satellites.
• It is 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.

About Haiyang-2D (HY-2D) satellite

• It was developed by the China Academy of Space Technology, while the carrier rocket was developed by the Shanghai Academy of Spaceflight Technology.
• It will form a constellation with the HY-2B and HY-2C satellites to build an all-weather and round-the-clock dynamic ocean environment monitoring system.
• The constellation will support the country’s early warning and prediction of marine disasters, its sustainable development and utilization of ocean resources.
• It will help in effective response to global climate change as well as ocean research.
• The 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.
• The planned satellite network will be capable of carrying out 80 percent of the world’s sea surface wind monitoring within six hours.
• The follow-up network of HY-2 satellites will provide data support for marine disaster relief, meteorology, transportation and scientific applications.
