This thesis reviews the performance of the first Passive Hydrogen Maser (PHM) launched by the Galileo system in 2008; and demonstrates how the new PHM can be consider as the best clock in space, pushing the physical clock error contribution below the noise floor of geodetic time transfer capabilities. Furthermore, overall GNSS clock peformance is reviewed UR - https://www.ksp.kit.edu/9783731501121 UR - https://directory.doabooks.org/handle/20.500.12854/56003 ER -
