TAI Time Links with Geodetic Receivers: A Progress Report

Abstract

In April 2002, a pilot experiment (TAIP3) was proposed by the BIPM to laboratories participating to TAI in order to study the use of GPS P3 code measurements obtained with calibrated receivers of the type Ashtech Z12-T or equivalent to compute time links. First data were submitted in June 2002 and, by the end of 2002, close to ten laboratories routinely submitted such data. This paper presents the results of several time links computed with this data set and compares them to those obtained by other time transfer techniques. The achieved stability shows improvements with respect to other techniques presently used for TAI links and the achieved accuracy is consistent with that expected from uncertainty in calibration.
