| Abstract: | In satellite navigation and positioning system,the high performance atomic clocks take an important place.In particular the on-board clocks which are key component to reach the positioning performance.Since its creation,the GPS system has already used two different tech- nologies,Rb clocks and Cs clocks.Concerning the Galileo system,two technologies are specified for the first generation of satellite.The first one is also a Rb clock while the second is a passive H maser,which has not been spatialized before... |
