| Zusammenfassung | The Ku-band transatlantic and Europe-to-Europe two-way satellite time and frequency transfer (TWSTFT) operations used 2.5 MChip/s pseudo-random codes with 3.5 MHz bandwidth until the end of July 2009. The cost of TWSTFT operation is associated with the bandwidth used on a geostationary satellite. The transatlantic and Europe-to-Europe TWSTFT operations faced a significant increase in cost for using 3.5 MHz bandwidth on a new satellite. The use of 1 MChip/s pseudo-random codes with 2.5 MHz bandwidth was one of the alternatives for continuing the TWSTFT operations without the increase in cost. Two timing laboratories in the US and eight timing laboratories in Europe participated in an experiment from February to July of 2009 to study the 1 MChip/s TWSTFT performance. Based on the study results, the transatlantic and Europe-to-Europe TWSTFT operations switched to a new satellite using 1 MChip/s codes with 2.5 MHz bandwidth since 1 August 2009. In this paper, we report the performance of 1 MChip/s TWSTFT for the transatlantic and Europe-to-Europe links. |
