作为引力波高能电磁对应体全天监视器(GECAM)星座的一员，GECAM-C是搭载于SATech-01实验卫星上的全天γ射线监视器，具有在轨触发能力。在太阳同步轨道运行期间，GECAM-C产生大量在轨触发事件，其中部分对应重要的天体物理爆发现象，如γ射线暴和软γ射线重复暴，这些可能需要后续观测。然而，也存在大量非天体物理触发事件，如粒子事件。因此，对在轨触发事件进行快速准确的分类对科学研究至关重要。本研究提出了一种基于贝叶斯推断的GECAM-C在轨触发自动分类算法。将该算法应用于2022年12月至2023年12月的GECAM-C触发数据，结果表明其能够以约95%的准确率成功分类所有触发类型，从而为快速后续观测提供有效支持。
