On June 8, my country used the Long March 3B carrier rocket at the Xichang Satellite Launch Center to successfully put the Fengyun 4-02 satellite into the predetermined orbit, and the launch mission was a complete success. Fengyun-4 02 is the first operational satellite of my country’s new generation of geostationary orbiting meteorological satellites. It is mainly used in weather analysis and forecasting, environmental and disaster monitoring and other fields. The Shanghai Institute of Technical Physics of the Chinese Academy of Sciences has undertaken the development of all the main payloads of the satellite—interferometric infrared detectors, radiation imagers, and fast imagers.
The interferometric infrared detector can provide three-dimensional atmospheric change information for numerical weather forecasting; the multi-channel scanning imaging radiometer can provide high-precision multi-spectral monitoring services for weather forecast warning; the new payload fast imager can meet the needs of short-term nowcasting Provides regional high-resolution day and night continuous rapid monitoring at better than 1 minute intervals. These payloads will play an important role in weather forecasting, climate prediction, and environmental and disaster monitoring, further improving the accuracy and refinement of my country’s weather forecasting.
On the basis of fully inheriting the technology of Fengyun-4 A star, the related payload of B star has achieved system upgrade and optimization. Interferometric infrared detectors can achieve wider band and higher spatial resolution detection, enabling my country to continue to maintain international leadership in the ability to detect three-dimensional atmospheres in geostationary orbits; radiation imagers have improved spectral accuracy and imaging sensitivity, and added low-level water vapor channels. Optimized 3-band spectral settings to enhance quantitative observation of the Earth’s surface and clouds.
The FY-4B satellite payload will start up and work gradually after the satellite is fixed, and will realize the dual-satellite network business operation of my country’s new generation of geostationary orbit meteorological satellites with the A satellite currently in orbit.
The Shanghai Institute of Technical Physics of the Chinese Academy of Sciences was founded in October 1958 by the Shanghai Branch of the Chinese Academy of Sciences and Fudan University. It was established independently in 1961 and is affiliated to the Chinese Academy of Sciences. It is the backbone unit and main R&D unit in the field of infrared and optoelectronic technology in China.
Shanghai Institute of Technical Physics, Chinese Academy of Sciences (referred to as Shanghai Institute of Technical Physics) is a comprehensive research institution integrating basic research, engineering technology research and development and high-tech industrialization. Shanghai Jiwu Institute takes infrared physics and optoelectronic technology research as its orientation, takes infrared optoelectronic new materials, new devices, and new methods as its main research direction, focusing on the development of advanced aerospace payloads, infrared staring imaging and signal processing, infrared focal plane and Remote sensing information processing and other technologies.
