Portable Hydrogen Maser Clock Time Transfer at the Subnanosecond Level
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.
