A Long March-2C rocket carrying the HY-1C satellite took off at 11:15 a.m. from the Taiyuan Satellite Launch Center in north China's Shanxi Province.
The satellite will assist in monitoring ocean colour and water temperatures, providing basic data for research on the global oceanic environment, reports Xinhua, citing the State Administration of Science, Technology and Industry for National Defence (SASTIND), which oversees China's space activities.
Its data will also be used in the survey of the resources and environment of China's offshore waters, islands and coastal zones, marine disaster relief and the sustainable utilization of ocean resources, said the administration.
With a design life of five years, it was developed by the China Spacesat Co, Ltd under the China Academy of Space Technology.
HY-1C can detect chlorophyll and suspended sediment concentrations and dissolved organic matter, which can affect ocean colour, as well as temperatures on the sea surface, said Wang Lili, chief designer of the satellite.
