外文摘要：Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor(GECAM),consisting of two micro-satellites,is designed to detect gamma-ray bursts associated with gravitational-wave events.Here,we introduce the real-time burst alert system of GECAM,with the adoption of the BeiDou-3 short message communication service.We present the post-trigger operations,the detailed ground-based analysis,and the performance of the system.In the first year of the in-flight operation,GECAM was triggered by 42 gamma-ray bursts.The GECAM real-time burst alert system has the ability to distribute the alert within∼1 minute after being triggered,which enables timely follow-up observations.
