Haiyang-1C launched by Long March 2C
On September 7, 2018, China launched its third ocean survey satellite of the Haiyang-1 series on Friday, with the launch taking place from the Taiyuan Satellite Launching Center at 03:15 UTC. A Long March-2C (Chang Zheng-2C) rocket was used to loft the new satellite.
Haiyang-1C will be used to monitor and prevent oceanic pollution, resource investigation, construction of bayou and ports, and for the development of coastal areas, using the system to monitor ocean temperatures.
Haiyang-1C (HY-1C) launched by Long March-2C
Onboard HY-1C there are two instruments: The China Ocean Colour & Temperature Scanner (COCTS), a medium-resolution optical imager developed by SITP (Shanghai Institute of Technical Physics) of CAS (China Academy of Sciences), and the Coastal Zone Imager (CZI), a multispectral push broom CCD instrument developed by the Beijing Institute of Space Machines and Electricity, CAST.
Developed for measuring the ocean color and sea surface temperature, the 50 kg COCTS will be used for determining the Aerosol Optical Depth, Aerosol column burden, biomass, the Colour Dissolved Organic Matter (CDOM) and the Earth surface albedo.

The 15 kg CZI will be used to analyze the vegetation and coastal zone, determining the biomass, the Fraction of Absorbed PAR (FAPAR), Fraction of vegetated land, Land cover and the Leaf Area Index (LAI). The CZI used on Haiyang-1C was improved to 50 m resolution (from 250 m from the Haiyang-1B) and also has a wider image swath.
HY-1C is now able to image at up to 20 degrees pitch angles which would minimize problems from sun spots. The satellite lifetime is now five years (up from 3-5 years on HY-1B).
