Summary
GECAM launched on a China Aerospace Science and Technology Corporation Long March 11 from Mobile Launcher Pad, Xichang Satellite Launch Center, People's Republic of China on December 9, 2020. It was China Aerospace Science and Technology Corporation's 302nd launch, 32nd this year and humanity's 6,026th orbital launch attempt. It was the 11th Long March 11 flight and the 3rd this year. The payload was bound for low Earth orbit (LEO). Xiaoji, one of 4 catalogued objects, reached a 595 × 611 km orbit inclined 29.0°. 4 objects from this launch are catalogued, 2 of them payloads.

About this launch
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.
