title = "Combined multi-system GNSS analysis for time and frequency transfer",
abstract = "The Center for Orbit Determination in Europe (CODE) is one of the Analysis Centers (AC) of the International GNSS Service (IGS). It is located at the Astronomical Institute of the University of Bern (AIUB). Since May 2003, CODE provides consistent GPS and GLONASS satellite orbits from a combined analysis using the Bernese GPS Software package. The data of about 30 stations in the IGS network that are equipped with GNSS receivers tracking GPS as well as GLONASS satellites are analyzed for that purpose together with numerous stations that only track the GPS satellites.",
