China successfully launches new ocean observation satellite

The constellation will support the country's early warning and prediction of marine disasters.

China on Wednesday successfully sent a new ocean-monitoring satellite into orbit as part of its effort to build an all-weather and round-the-clock dynamic ocean environment monitoring system which would provide early warning on marine disasters. The satellite was launched by a Long March-4B rocket carrying the Haiyang-2D (HY-2D) satellite from the Jiuquan Satellite Launch Centre in northwest China, the state media reported. The HY-2D will form a constellation with the HY-2B and HY-2C satellites to build an all-weather and round-the-clock dynamic ocean environment monitoring system of high frequency and medium and large scale, Xinhua reported.
