The PHM is an atomic clock with outstanding stability for averaging times from 1 to 100, 000 seconds, to be used in precise positioning, time keeping and other on-boards applications. It is designed to perform in space environment for not less than 12 years. The operating principle exploits the stimulated energy emission occurring during the hyperfine transition of the atomic hydrogen in a miniaturised microwave cavity. The ultra stable RF [Radio Frequency] generated signal, at the frequency of 1420. 4057517..

Le maser ("Microwave Amplification by Stimulated Emission of Radiation") à hydrogène est une horloge atomique extrêmement stable basée sur l'atome d'hydrogène. Il a été inventé par Kleppner et Ramsey en 1960 à l'université de Harvard. Le principe de fonctionnement est semblable à celui du LASER sauf que la radiation émise est une radiation micro-onde et non pas optique. Le maser à hydrogène est utilisé principalement en radioastronomie et en géodésie comme horloge pour la synchronisation de radiotélescopes utilisant la technique du VLBI (Very Long Base Interferometry). Il est utilisé également pour la poursuite des sondes planétaires (Deep Space Tracking). Dans le futur, il pourrait être utilisé dans les systèmes de navigation par satellite de type GPS à cause de sa très grande stabilité (cf l'avenir du temps atomique ). 3, record 4, French, - maser%20%C3%A0%20hydrog%C3%A8ne%20passif

The former is measured by varying the intensity of a reference tone until it appears to a listener to be as loud as the sound stimulus under test.

Record number: 9, Textual support number: 1 OBS
For static positioning, the reconstructed carrier phase is sampled at epochs determined by a clock in the receiver. The reconstructed carrier phase changes according to the continuously integrated Doppler shift of the incoming signal, biased by the integral of the frequency offset between the satellite and receiver reference oscillators. The reconstructed carrier phase can be related to the satellite-to-receiver range, once the initial range(or phase ambiguity) has been determined. A change in the satellite-to-receiver range of one wavelength of the GPS carrier(19 cm for L1) will result in a one-cycle change in the phase of the reconstructed carrier. 1, record 9, English, - reconstructed%20carrier%20phase
