|Title:||Two-Way Satellite Time and Frequency Transfer Using 1 MChip/S codes|
|Published:||November 16, 2009|
|Abstract:||The Ku-band transatlantic and Europe to Europe two-way satellite time and frequency transfer (TWSTFT) operations used the 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 the Europe to Europe TWSTFT operations faced a steep cost increase for using the 3.5 MHz bandwidth on a new satellite. The use of the 1 MChip/s pseudo-random codes with 2.5 MHz bandwidth was one of the alternatives for continuing the TWSTFT operations without the cost increase. 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 the Europe to Europe TWSTFT operations have switched to a new satellite using the 1 MChip/s codes with 2.5 MHz bandwidth since August 1, 2009. In this paper, we report the performance of 1 MChip/s TWSTFT for the transatlantic and the Europe to Europe links.|
