The satellite will fill the gap in China's high-precision global ocean-salinity detection capabilities, improve data collection on ocean dynamics and environmental factors, and boost the accuracy of China's marine forecasting products.

It will also support marine environmental forecasting, ecological forecasting, water-cycle monitoring, short-term climate prediction, and global climate change research, providing critical data for applications in agriculture, disaster mitigation, meteorology, and other related industries.

It was the 545th flight mission of the Long March series rockets.
