PORTABLE HYDROGEN MASER CLOCK TIME TRANSFER AT THE SUBNANOSECOND LEVEL

L.J. Rueger, M.C. Chiu, S.D. Deines

Abstract:	A subnanosecond time transfer between the Johns Hopkins University Applied Physics Laboratory (JHU/APL) and the United States Naval Observatory (USNO) was carried out using a portable hydrogen maser. The maser was contained within a temperature controlled enclosure which was supported on pneumatic shock isolators Inside an air-conditioned van. The comparisons of the portable maser time with the APL base station maser time used the National Bureau of Standards technique of dual balanced mixers with picosecond resolution.
