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 606 $aPhysics$2bicssc 610 $aAtomic Clocks 610 $aclock performance 610 $aGNSS 610 $aSatellite Navigation 610 $aTime prediction 615 7$aPhysics 700 $aGonzalez Martinez$b Francisco Javier$4auth$01323457 906 $aBOOK 912 $a9910347059203321 996 $aPerformance of new GNSS satellite clocks$93035576 997 $aUNINA
