According to an expert from the Fifth Academy of China Aerospace Science and Technology Corporation, the newly launched Haiyang-2E will operate as the successor to the Haiyang-2B launched in 2018 and, together with the currently operating Haiyang-2C and 2D, will ensure the continuous and stable operation of China’s ocean dynamics and marine environment monitoring missions.

Haiyang-2E is equipped with four main microwave remote sensing instruments: a radar altimeter, a microwave scatterometer, a microwave radiometer, and a calibration radiometer. It collects high-precision data on sea surface height, significant wave height, marine wind conditions, sea surface temperature, and other parameters, providing a key data foundation for marine weather forecasting and research on phenomena like El Niño.

The Haiyang-2 series satellites not only contribute to marine weather and disaster prevention and mitigation but are also closely involved in the development of ‘blue food.’ The series’ collected data on wind, waves, and ocean currents are used to analyze distant fishing grounds and predict fishing conditions, serving as an information base that supports scientific and efficient operations in China’s distant-water fisheries.

The Haiyang-2B, the series has also included AIS (Automatic Identification System) equipment which allows for uninterrupted acquisition of information such as ship positions, navigation speed, and call signs.
