On May 1st, reports indicate that the Fengyun-3G Satellite G has officially entered operational service. Prior to this, the satellite not only successfully passed the acceptance of trial operation and the review of operational plans but also received unanimous approval from an expert group. Its satellite-ground system's operational status fully meets the operational standards, marking the maturity of Fengyun-3G Satellite G for formal operational service.
Launched on April 16, 2023, the Fengyun-3G Satellite G is a milestone satellite as China's first low-inclination orbit precipitation measurement satellite. Its unique mission involves in-depth research on precipitation climatology and real-time monitoring of precipitation in hazardous weather systems, providing researchers with three-dimensional structural information on precipitation in the global mid-low latitude regions.
The successful launch of this significant satellite has propelled China to achieve remarkable success in global meteorological observation, making it the only country in the world operating four near-earth orbit civil meteorological satellites simultaneously in the morning, evening, morning, afternoon, and inclined orbits. This showcases China's leading position in meteorological science and technology.
Since October 23, 2023, Fengyun-3G Satellite G has undergone over six months of operational trial operation. Throughout this period, the satellite-ground system has maintained a robust operational status, demonstrating outstanding performance in satellite platform, onboard payloads, satellite telemetry, tracking, and control. The success rates of data reception, processing, distribution, and archiving have all met the preset standards, fully proving its capability for formal operational service.
During the in-orbit testing and trial operation period, Fengyun-3G Satellite G has played a crucial role in various important occasions and events. It has effectively participated in the analysis of high-impact weather during the flood season, providing accurate meteorological services for major events such as the Chengdu Universiade and the Hangzhou Asian Games. Moreover, it has successfully detected the three-dimensional structure of extreme rainfall in countries like Brazil and the Maldives, offering valuable meteorological data support to the international community.
