A Study Examining the Possibility of Obtaining Traceability to UK National Standards of Time and Frequency Using GPS-Disciplined Oscillators

Abstract

In the UK there is considerable interest in using GPS-Disciplined Oscillators (GPSDOs) as standards traceable to UTC(NPL). However, UK accreditation bodies are somewhat reluctant to accept GPSDOs as traceable standards, without a detailed study of the practical issues involved in establishing traceability. NPL has undertaken an extensive study, examining the performance of 15 GPSDOs loaned by 11 UK suppliers and manufacturers, to address this traceability issue. In this paper a detailed account is presented of the results obtained from the NPL study. A preliminary set of recommendations on the use of GPSDOs as standards traceable to UTC(NPL) have been produced. The progress made on implementing a mechanism enabling GPSDOs to be recognized as standards traceable to UTC(NPL) is outlined.
