Extreme Energy Events (EEE) is an extended Cosmic Rays (CRs) Observatory, composed of about 60 tracking telescopes spread over more than 10 degrees in Latitude and Longitude. We present the metrological characterization of a representative set of actually installed EEE GPS receivers, their calibration and their comparison with respect to dual-frequency receivers for timing applications, as well as plans for a transportable measurement system to calibrate the currently deployed GPS receivers. Finally, the realization of an INRIM Laboratory dedicated to EEE, aimed at hosting reference telescopes and allowing timing studies for Particle Physics/Astrophysics experiments, is presented, as well as the possibility of synchronizing already deployed telescopes utilizing White Rabbit Technique, over optical fiber links, directly with the Universal Time Coordinated time scale, as realized by INRIM (UTC(IT)).

广泛的宇宙阵雨探测:定时的重要性和 GPS 在 EEE 实验中的作用

极端能量事件 (EEE) 是一个扩展的宇宙射线 (CRs) 天文台,由大约 60 个跟踪望远镜组成,分布在纬度和经度超过 10 度的范围内。我们介绍了一组具有代表性的实际安装的 EEE GPS 接收器的计量特性、它们的校准以及它们与用于计时应用的双频接收器的比较,以及用于校准当前部署的 GPS 接收器的便携式测量系统的计划。最后,介绍了致力于 EEE 的 INRIM 实验室的实现,该实验室旨在托管参考望远镜并允许粒子物理/天体物理学实验的时间研究,以及利用白兔技术通过光纤链路同步已部署望远镜的可能性,
