Galileo Common View: Format, Processing, and Tests with GIOVE

Abstract : R2CGGTTS is a software program dedicated to provide clock solutions for GNSS time transfer in the standard CGGTTS (Common GPS GLONASS Time Transfer Standard) from RINEX observation files. This paper presents the upgrade of the R2CGGTTS to include observations of the future Galileo satellites; the approach is validated using the GIOVE data. A second part of the paper presents the possibilities of the future Galileo E5 signal, of which the very small noise level promises a large improvement to the GNSS time transfer accuracy.
