China will launch four ocean-observation satellites within the coming 16 months. Two will be launched in September and November this year, and the other two will be sent into space in 2021, according to the World Marine Science and Technology Conference.

As of August, China has independently developed and launched seven Haiyang satellites, named after the Chinese word for "ocean" and given the "HY" designation for short.

The country launched its first ocean-monitoring satellite, the HY-1A, on May 15, 2002, and sent HY-1D into orbit in June this year.

The space-based remote-sensing technology has been used in fields such as marine environmental resources survey, marine disaster prevention and alleviation, marine economy, marine ecology and maritime security, according to a sub-forum of the World Marine Science and Technology Conference.

The HY-2A and HY-2B satellites can monitor typhoons in the northwest Pacific region and capture information on all the typhoons throughout the year, providing support for typhoon forecasting during the flood season.
