Abstract:	The relative calibration of the GPS time link between European Organization for Nuclear Research (CERN) and Gran Sasso National Laboratory (LNGS), performed in 2011, is reviewed. “Relative” means that traveling equipment was used to calibrate the delay of the link as a whole, but no information on absolute delays of individual components was gained. The precisely calibrated GPS link was used in the framework of the measurement of the time of flight of neutrinos generated in the CERN Neutrino to Gran Sasso (CNGS) experiment and measured with the Oscillation Project with Emulsion Tracking Apparatus (OPERA) detector at LNGS.
