Abstract

The international transatlantic time and frequency transfer experiment was designed by participating laboratories and has been implemented during 1994 to test the international communications path involving a large number of transmitting stations. This paper will present empirically determined clock and time scale differences, time and frequency domain instabilities, and a representative power spectral density analysis. The experiments by the method of co-location which will allow absolute calibration of the participating laboratories have been performed. Absolute time differences and accuracy levels of this experiment will be assessed in the near future., Presented at the Annual Precise Time and Time Interval (PTTI) Applications and Planning Meeting (26th) held in Reston, VA on 6-8 December 1994. Published in the Proceedings of the Annual Precise Time and Time Interval (PTTI) Applications and Planning Meeting (26th), p39-50, December 1994.
