Tests of the BIPM Portable Calibration Station - METODE: MEasurement of TOtal Delay

Z. Jiang, L. Tisserand, and G. Petit

Abstract:	The dominant part of the total uncertainty budget in the UTC time transfer is from the time transfer link calibration. To improve the calibration, the BIPM is developing a standard calibration procedure in which we use a portable calibration station. It is composed of a 10 MHz distributor, a PPS distributor and two GNSS geodetic systems each including a set of an independent receiver and an antenna. The station is integrated and pre-cabled. The visited laboratory should provide the 10 MHz signal and the 1 PPS signal with a known delay to the laboratory reference. The goal is to provide a link calibration with a 2 ns type B uncertainty for UTC time transfer. In this paper, we outline the first experiments carried out on the common-clock zero and short baselines at the BIPM.
