"Each satellite can see the globe twice a day for morning and evening. And for two satellites, it will be four times [for the whole day]. So, the overall observation efficiency will be doubled."

China's first civil-use satellite constellation will be formed, when the newly launched ocean-monitoring satellite HY-1D stays in orbit.

Carried by Long March-2C rocket, the HY-1D was sent into space from the Taiyuan Satellite Launch Center in north China's Shanxi Province on Thursday, according to the China National Space Administration. After operating into orbit, HY-1D will cooperate with its predecessor satellite HY-1C, which was launched in September 2018, to increase the country's ability to observe global ocean color, coastal zone resources and the ecological environment.

Previously, the country's ocean observation satellites could only be able to collect data in the morning across the globe. But the satellite constellation will help fill the gap of afternoon global ocean data for China, when it is formed. And with the help of the two satellites, the efficiency of data collection will be greatly improved.

"Each satellite can see the globe twice a day for morning and evening. And for two satellites, it will be four times [for the whole day]. So, the overall observation efficiency will be doubled," said Bai Zhaoguang, director of science and technology commission with China Spacesat Co., Ltd, and also an expert in research and development of HY-1 series satellites.

The data may also be used to facilitate marine disaster prevention and mitigation, sustainable utilization of marine resources, marine ecological early warning and environmental protection.

The HY-1D, passing factory tests in May this year, is the country's fourth satellite for monitoring ocean color and an operational satellite for China's civil space infrastructure system.
