Abstract

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 a center frequency of 70 MHz. Instead of using 3.5 MHz bandwidth required for the 2.5 MChip/s signal, the use of SAW filters allows the 2.5 MChip/s TWSTFT to use only 2.5 MHz bandwidth on a satellite transponder. We evaluated the SAW filters. We compared the time transfer instability of the filtered 2.5 MChip/s TWSTFT to the 1 MChip/s TWSTFT with and without the SAW filters. This paper presents the experiment results.
