A direct comparaison between two independently calibrated time transfer techniques: T2L2 and GPS Common-Vews
Résumé
This paper presents a direct comparison of two time transfer techniques on independently calibrated links: Time Transfer by Laser Link (T2L2) and Global Positioning System (GPS) satellite common-views (CV). The two different techniques are described, along with the independent link calibrations. The results achieved during one measurement campaign involving three European laboratories are presented, the differences be- tween the two techniques remaining in average below 300 ps, with a standard-deviation below 500 ps mostly due to GPS CV.
