China Launches New Earth Observation Satellite

China launched Beijing-3B on 24 August 2022, a commercial Earth-observation satellite designed for 0.5-meter optical imagery.

24 Aug 2022: One day after the KZ-1A launch from Xichang, China launched a Long March 2D with the Beijing-3B Earth Observation satellite from Taiyuan. BJ-3B is reported to be capable of 0.5m-resolution imagery. Twenty First Century Aerospace Technology Co., Ltd. (21AT), a commercial space company, operates the satellite along with its BJ-3A predecessor. Launch Video.

– BJ-3B is in a polar sun-synchronous orbit at approximately 596 x 615km and 97.9° inclination.

– BJ-3B is designed to provide high-resolution remote-sensing data products; its optical system is capable of 0.5-meter resolution.

– The initial Beijing-3 satellite, BJ-3A, launched in Nov 2021 and carries two imagers: a full-color imager with 0.5m resolution and a multispectral imager with 2.0m resolution.

Beijing-3 is described as China’s most agile satellite built to date, able to photograph large areas quickly through onboard AI stabilization. It can also plan its flight route independently while monitoring up to 500 areas of interest as it orbits the globe nearly 15 times each day.
