From August 2010 to April 2011, NIST and OP conducted an experiment of using surface acoustic wave (SAW) filters in transatlantic two-way satellite time and frequency transfer (TWSTFT) with 2.5 MChip/s pseudo-random noise (PRN) codes. The SAW filters used in the experiment are 2.5 MHz band-pass filters with center frequency at 70 MHz. We evaluated the SAW filters. We studied time transfer instability of the filtered 2.5 MChip/s TWSTFT by comparisons to time transfer instability of the 1 MChip/s TWSTFT with and without the SAW filters. This paper presents the experiment results.
