摘要
暴的实时触发与定位是 GECAM 的关键功能，GECAM 是于 2020 年 12 月 10 日发射的全天伽马射线监视器。我们开发了一款运行于 GECAM 电子学机箱（EBOX）CPU 上的多功能触发与定位软件。该星上软件具有以下特点：对真实天体暴具有高触发效率，并能抑制由带电粒子暴和背景涨落引起的假触发；分别针对短暴和长暴优化的专用定位算法；通过北斗卫星导航系统（BDS）下传的触发信息具有短时间延迟。本文介绍了 GECAM 触发与定位软件系统的详细设计与开发，包括主要功能、总体设计、工作流程与算法，以及该软件的验证与演示，包括使用专用 X 射线管模拟伽马射线暴的地面触发测试，以及对真实伽马射线暴和磁星暴的在轨表现。
