HY 2A [CAST]
HY 2 (Haiyang = Ocean) is a chinese series of Earth observation satellites focused on the marine dynamic environment.
The objective of the 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), a scatterometer and a microwave imager.
HY 2A was launched by a CZ-4B launch vehicle from Taiyuan Satellite Launch Center in August 2011.
HY 2B followed on 24 October 2018 again on a CZ-4B launch vehicle from Taiyuan Satellite Launch Center.
