HY-2 satellites have precisely captured typhoon data during typhoon activities affecting China, played an important role in tsunami early warning, and provided data to global numerical weather prediction systems.
The wind, wave and current data obtained by HY-2 satellites can also help analyze major ocean fishing grounds, enabling fishermen to locate fish schools with precision and efficiency, thereby increasing catch yields and reducing offshore operating costs.
The Automatic Identification System (AIS) for vessels has also been added to HY-2 satellites since HY-2B, enabling continuous acquisition of vessel position, speed and call sign to improve navigation security.
