Abstract:

A subnanosecond time transfer between the Johns Hopkins University Applied Physics Laboratory JHUAPL 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.
