China launched a new satellite for ocean observation from the Taiyuan Satellite Launch Center on Wednesday. Launch of the Haiyang-2B took place at 22:57 UTC from the LC9 Launch Complex. The new satellite was orbited by a Long March-4B (Chang Zheng-4B) launch vehicle.
The Haiyang-2 program represents the second generation of ocean observation and monitorization satellites, with the program being approved by the China National Space Administration on February 2007, for measurement of ocean dynamic and environmental parameters in the microwave region (permitting all weather observations).
The requirements call also for the collection of data on marine wind setup (wind vector), marine surface height, and SST (Sea Surface Temperature), along with aero-marine forecasts for the prevention and relief of disaster.
The design and development of the HY-2 series began in April 2007, with the program funded by the Chinese State Oceanic Administration. The satellites are operated by the National Satellite Ocean Application Service.
The Haiyang-2 satellites are part of a system consisting of ocean color remote sensing satellites, ocean dynamic environment satellites and ocean surveillance satellites. The color remote sensing satellites use infrared remote sensing technology to monitor ocean pollution and topography in shallow waters.
The Haiyang-2 dynamic environment satellites utilize microwave remote sensing technology to monitor ocean wind fields and ocean surface temperatures, and the Haiyang-3 ocean surveillance satellites will have the combined features of the Haiyang-1 and Haiyang-2 series.
