description Fengyun-3A Overview
Fengyun-3A is a Chinese polar-orbiting meteorological satellite launched on May 27, 2008, from the Taiyuan Satellite Launch Center. As the first spacecraft in China's second-generation polar-orbiting weather satellite series, it carried 11 instruments for atmospheric sounding, earth observation, and space environment monitoring. Operated by the China Meteorological Administration, Fengyun-3A supported numerical weather prediction, climate monitoring, and disaster management. It operated in a sun-synchronous orbit at approximately 870 km altitude.
help Fengyun-3A FAQ
What was Fengyun-3A built to do?
Fengyun-3A is a polar-orbiting meteorological satellite for observing the atmosphere, clouds, land, and ocean. It carried 11 instruments, including the MERSI imager, microwave sounders, and a space-environment monitor.
When and where was Fengyun-3A launched?
It launched on 27 May 2008 from the Taiyuan Satellite Launch Center in China. The mission was the first spacecraft in China's second-generation Fengyun-3 polar weather-satellite series.
What does polar or sun-synchronous orbit mean for FY-3A?
A near-polar sun-synchronous orbit lets FY-3A pass over different parts of Earth while keeping a fairly consistent local solar time for observations. That repeatable lighting helps weather services compare images and measurements from one pass to the next.
Was Fengyun-3A followed by another FY-3 satellite?
Yes, Fengyun-3B followed it and launched on 5 November 2010. FY-3A and FY-3B formed the opening pair of China's second-generation polar-orbiting meteorological program.
