Ocean satellites
CASC developed two HY-1 ocean color satellites and launched in 2002 and 2007 respectively. It was used to provide scientific base and basic data for the exploitation of halo-bios resources, coastal engineering, outfalls and harbors regulation, ocean environment survey, environment protection, and etc. The satellites can observe the optical characters of seawater, chlorophyll concentration, sea surface temperature, suspended sediment content, dissolved organic matter and ocean pollution, as well as seawater, shallow sea topography, ocean current character, atmospheric aerosols surface. And they also can learn the distribution of ocean primary productivity, the resources situation and the environmental quality of marine fishery and aquaculture, understand the distribution of suspended sediment of major outfalls and harbors. HY-1 satellite has achieved the world leading level. HY-2 satellite is under development by China Academy of Space Technology (CAST). HY satellites would be expanded in terms of series.
