Summary
GECAM-B, also known as Xiaomu, is a satellite launched on December 9, 2020, from Xichang Satellite Launch Center (XICLF) using the Chang Zheng 11 launch vehicle. The spacecraft measures 1 meter in length with a diameter of 0.3 meters and spans 1.5 meters when its deployable solar array is extended. It has a dry mass of 150 kilograms, which was also its launch mass. GECAM-B is part of the Chinese Academy of Sciences (CAS) mission aimed at astronomy, specifically X-Ray / Gamma research. Its primary equipment includes a dome-shaped array consisting of 25 Gamma-ray detectors and 8 Charged particle detectors. The satellite's shape can be described as a box with a dome and one panel, and it was manufactured by SECM (Satellite Engineering Center for Microsatellites).
