长征 11 | GECAM

GECAM (Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor) is a constellation of two small X-ray and gamma-ray all-sky observatories to search for gamma-ray counterparts to gravitational wave events. Each satellite features a dome-shaped array of 25 Gamma-ray detectors (GRD) and 8 Charged particle detectors (CPD). Together the satellites will provide a FOV of 100% all-sky. The sensitivity of the detectors is ~2E-8 erg/cm2/s. They will provide a localization of ~1°. The detectors are sensible in the energy band from 6 keV to 5 MeV. Besides detecting the radiation from gravitatinal wave events, the satellites will also be contributing in detectiong Ultra-long GRBs, X-ray Flashes, X-ray-rich GRBs, Magnetars and Terrestrial Gamma-ray Flashes.

GECAM卫星（引力波高能电磁对应体全天监测器，Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor）是由两颗小型X射线和伽马射线全天观测卫星组成的星座，用于搜索引力波事件的伽马射线对应体。 每颗卫星配备一个圆顶形阵列，包含25个伽马射线探测器（GRD）和8个带电粒子探测器（CPD）。两颗卫星一起将提供100%全天视场。探测器的灵敏度约为2E-8 erg/cm2/s。它们将提供约1°的定位精度。探测器在6 keV至5 MeV的能量范围内敏感。 除了探测引力波事件的辐射外，这些卫星还将有助于探测超长伽马射线暴（Ultra-long GRBs）、X射线闪（X-ray Flashes）、富X射线伽马射线暴（X-ray-rich GRBs）、磁星（Magnetars）和地球伽马射线闪（Terrestrial Gamma-ray Flashes）。
