Rapid transatlantic time transfer: Surveying the link between USNO and IEN within the IGS global real-time network

This paper reports on the capability of rapid time/frequency transfer, surveying the transatlantic link between timing laboratories of the U.S. Naval Observatory (USNO, Washington D.C., USA) and the Istituto Nazionale di Ricerca Metrologica (I.N.RI.M., Torino, Italy). Over a six month period, the near-real-time estimation of the UTC(USNO) to UTC(IEN) offset computed by Natural Resources Canada (NRCan) is directly compared with BIPM Circular T data and other independent synchronization techniques, such as TWSTFT.
