On the 16th April 2023 clear 0936 Hours Hong Kong SAR- Beijing time , the Belt and Road Initiative CNSA –China National Space Administration launching from Jiuquan Satellite Launch Center – Inner Mongolia –China – People’s Republic of China deployed launched the Chang Zheng – The Chang Zheng – Long March 4B Y51 carrier rocket.. This launch is the 471st launch of the Long March series of launch vehicles.
Successfully launched the Fengyun-3G satellite, and my country has entered a new stage of active precipitation measurement and detection.. At 9:36 Hong Kong SAR- Beijing Time today, the Long March 4B Yao 51 carrier rocket was ignited and blasted off at the Jiuquan Satellite Launch Center, successfully carrying my country’s first The first precipitation measurement satellite Fengyun-3G was sent into the predetermined orbit, and the launch mission was a complete success……
Fengyun-3G satellite is China, People’s Republic of China first low-orbit non-sun-synchronous inclined orbit meteorological satellite, and it is also my country’s first and the third international active precipitation measurement satellite. The satellite is equipped with 4 units/sets of active precipitation measurement radar, microwave imager, medium-resolution spectral imager, and global navigation satellite occultation detector, which will fill the gap in domestic precipitation three-dimensional tomographic detection data. So far, my country has successfully launched a total of 20 “two-generation and four-type” Fengyun meteorological satellites.
The FY-3 G star is equipped with my country’s first set of “airborne rain gauge” – the satellite-borne Ku and Ka dual-frequency precipitation measurement radar, which transmits wireless electromagnetic wave signals to the atmosphere and receives the reflection signals of precipitation particles at different altitudes in the atmosphere to achieve vertical Detection of directional precipitation: Using the scanning ability of the radar in the cross-track direction, the detection of precipitation in the horizontal direction is realized, just like the “CT” scanning of atmospheric precipitation, to obtain the fine three-dimensional structure information of precipitation.
