Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) () is a space observatory composed of a constellation of two small telescope satellites(GECAM A and  GECAM B ) for research in electromagnetic counterparts of gravitational waves  . It was launched on 9 December 2020 from the Xichang Satellite Launch Center at 20:14 UTC  . GECAM will focus on detecting electromagnetic counterparts of gravitational waves. 
Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) () is a space observatory composed of a constellation of two X-ray and gamma-ray all-sky observing small satellites, called GECAM A (aka KX 08A or Xiaoji, COSPAR 2020-094A) and GECAM B (aka KX 08B or Xiaomu, COSPAR 2020-094B), for research in electromagnetic counterparts of gravitational waves (GWs) . It was launched on 9 December 2020 from the Xichang Satellite Launch Center at 20:14 UTC by a Long March 11 rocket . GECAM will focus on detecting electromagnetic counterparts of gravitational waves. In addition to signals from GWs, the observatory studies Ultra-long GRBs, X-ray Flashes, X-ray-rich GRBs, Magnetars and Terrestrial Gamma-ray URL
