HY (satellite)

HaiYang (Chinese: 海洋; "ocean"), abbreviated as HY, is a series of marine remote sensing satellites developed and operated by China since 2002. As of June 2020, six satellites were launched and two more are planned.[1][2]

For the city, see Haiyang.

The HaiYang series is operated by NSOAS (National Satellite Ocean Application Service), a subordinate agency of the State Oceanic Administration.
