| Zusammenfassung | The interoperability of the two satellite navigation systems Galileo and GPS shall be assured by, among other measures, broadcasting the actual difference between the two system times, Galileo System Time (GST) and GPS Time (GPST). The properties of PTB's time scale UTC(PTB) are in many aspects similar to what is expected for GST. Thus, the difference UTC(PTB) - GPST can be considered to be representative for the GST-GPST difference. UTC(PTB)-GPST was determined with the help of two methods, a TWSTFT link with USNO, and the restitution of GPST from the reception of the GPS Signal-In-Space (SIS) with GPS time receivers. Measurement data were collected between March 2003 and May 2004. Two independent TWSTFT links, one using a commercial telecommunication satellite (Ku-band), one using a US military communication satellite (X-band), were operated between USNO and PTB. USNO provided the required data UTC(USNO)-GPST. |
