The Fengyun-4 satellite represents a major leap forward in China's meteorological capabilities, significantly enhancing weather forecasting, disaster prevention, climate monitoring, ecological surveillance, and space weather early warning systems. It has become an essential tool across various sectors, especially in supporting China’s military-civilian integration strategy and playing a key role in the implementation of the "Belt and Road Initiative."
On September 25th, the new-generation geostationary meteorological satellite Fengyun-4 was officially handed over in Beijing. The satellite was delivered to the China Meteorological Administration by the China Aerospace Science and Technology Corporation, marking a milestone in China's space and meteorological development.
The successful on-orbit delivery of Fengyun-4 signifies the renewal of China’s geostationary meteorological satellite system. It ensures continuous, reliable, and stable operations for China’s geostationary meteorological observations, boosting the country’s international standing in both space technology and meteorology.
Fengyun-4 is the first satellite of the second generation of China’s geostationary meteorological satellites, transitioning from the earlier Fengyun-2 series. Developed by the China Aerospace Science and Technology Corporation, it was launched successfully in December 2016. During its orbital operations, all platform, payload, and ground application system tests were completed successfully. The results confirmed that the satellite meets all engineering requirements in terms of function and performance.
The development of Fengyun-4 has brought China’s geostationary meteorological satellite technology to an internationally advanced level, enabling a shift from merely "keeping up" to "leading" in this field. The satellite has filled three international technical gaps, including the world’s first interferometric hyperspectral atmospheric detection from geostationary orbit. It also features the first radiometer, lightning imager, and detector deployed on such a platform, operating continuously throughout the day. Additionally, it pioneered microwave detection technology at the 425GHz band.
During its on-orbit testing phase, the Fengyun-4 satellite conducted real-time and targeted monitoring of environmental and ecological issues, such as extreme weather events, cyanobacterial blooms, and desertification. These applications highlight its critical role in both scientific research and practical disaster management.

Industrial power supplies are power products specially designed and produced for a certain industrial production industry. For industrial power supplies, absolute balance of electronics characteristics is not the main focus. Different industrial applications focus on different specific electronics index, some focus on the stability of the power supply output voltage or current, but the ripple is not the key judging criteria; some industrial applications have customized requirements for power supplies, such as adding time control, adding pulse functions, adding multiple outputs, etc. At the same time, it is necessary to consider the cost requirements of large-scale purchases of industrial applications, so for industrial power supplies, Application adaptability, Long-term operating Reliability and Reasonable cost control are the main points of attention for industrial power supplies.
