In the development of a new time dissemination capability for the U.S. Air Force Eastern Missile Test Range, the satcom channels to be used became an issue in terms of performance over different links and available coverage. A primary advantage of C band is that satellite coverage is more widely available in remote areas where Ku coverage is limited or not available at all. To investigate the performance issue, a ...
For about one year the time scales UTC(OCA) and UTC(TUG) were compared by means of GPS and two-way satellite time transfer. At the end of the experiment both links were independently calibrated by measuring the differential delays of the GPS receivers and of the satellite earth stations by transportation of a GPS receiver and of one of the satellite terminals. The results obtained by both methods differ by about 3 ...
This very preliminary report briefly presents the first results on the time transfer experiments between TUG (Graz, Austria) and OCA (Grasse, France) using common view GPS, and two-way stations at both sites. The present data, providing a rms of the clock offsets of 2 to 3 nanoseconds for a three months period, have to be further analysed before any conclusions on the respective precision and accuracy of these techniques can ...
