China launches another high-res observation satellite
(20 Nov 2021) Rocket: Chang Zheng 4B; Payload: Gaofen-11 03; Date: 20 November 2021, 0151 UTC; Launch site: Taiyuan Satellite Launch Center, China. The satellites were deployed into 427 km x 439 km x 42.02 degrees orbits.
The launch marked the 397th mission for the Chang Zheng series rockets.
Gaofen 11-03 is the third in a series of high-resolution optical imaging Gaofen 11 satellites, part of the wider Gaofen series which aims to provide China with a global high-definition Earth-imaging capability for civil applications. Gaofen means "high resolution," and the Gaofen constellation is unrelated to the smaller commercial Jilin-1 Gaofen satellites.
The Gaofen 11 satellites operate in Sun-synchronous orbits, with a perigee of approximately 450 kilometers, an apogee of around 690 kilometers, and an inclination of 97.4 degrees.
