Comparison of two-way satellite time transfers and GPS common view time transfers

Abstract

The results are compared of remote clock synchronization obtained by two different techniques, i.e. GPS Common View and two-way satellite time transfers. Values for UTC (USNO)-UTC (NIST) published by the Bureau International des Poids et Mesures (BIPM) and the US National Institute of Standards and Technology (NIST), based on GPS common view data, are compared with values obtained by two-way satellite time transfers. The differences between the values published by NIST and those obtained by the two-way satellite technique do not seem to be significant.<>
