High Stability Sources  PHM (Passive Hydrogen Maser) is an atomic clock designed to perform in the space environment for a minimum of 12 years. With outstanding stability for averaging times ranging 1 to 100,000 seconds, it is used in precise positioning and time keeping. PHM is flying with excellent performances on-board the GIOVE B Satellite and has been selected as the reference clock for the Galileo Constellation.
