HY 2C, 2D
HY 2D [CAST]
HY 2 (Haiyang = Ocean) is a chinese series of Earth observation satellites focused on the marine dynamic environment.
The objective of the second batch of HY-2 satellites is to monitor the dynamic ocean environment with microwave sensors to detect sea surface wind field, sea surface height and sea surface temperature. The instrument suit consists of an altimeter (dual-frequency in Ku and C-bands), and a scatterometer.
These satellites are modified versions of the earlier HY 2A and 2B spacecraft. These satellites omit the microwave radiometer imager and feature two solar arrays.
HY 2C was launched in September 2020 on a CZ-4B launch vehicle from the Jiuquan Satellite Launch Center.
HY 2D followed in May 2021 also on a CZ-4B launch vehicle from the Jiuquan Satellite Launch Center.
