Abstract:	This study presents some first timing results obtained using the Galileo signals and the satellite orbits and clocks provided in the navigation messages. It is firstly shown how it is possible to determine the hardware delays of Galileo signals in a GNSS station already calibrated for GPS signals. Calibrated time transfer solutions between ORB and IT obtained from Galileo signals are then presented. Finally the Galileo dissemination of UTC and GPS to Galileo Time Offset (GGTO) are compared with respect to the same quantities estimated using a calibrated GNSS receiver.
