Abstract : This paper presents data obtained during an international time transfer experiment between the Bureau International de I'Heure (BIH), Paris, France; the Institut Fur Angewandte Geodasie (IFAG), Wettzell, Germany and the Bendix Field Engineering Corporation (BFEC), Columbia, Maryland utilizing GPS timing receivers developed for the NASA-Goddard Space Flight Center (GSFC) by the Naval Research Laboratory. The purpose of the experiment was to determine the accuracy of the GPS time transfer receivers for the NASA laser ranging network and to intercompare geographically separated atomic frequency standards. Two NASA-GSFC hydrogen masers and a high performance cesium beam frequency standard in thermally controlled chambers were used for the frequency baseline at BFEC. The IFAG frequency baseline was established using an EFOS-1 hydrogen maser and two Oscilloquartz cesium beam frequency standards.
