| Zusammenfassung |
| The absolute IGS antenna phase center model igs05.atx used since 2006
only includes a GPS-derived set of receiver antenna corrections. At the
time this model was compiled the GLONASS constellation was too weak to
perform reliable robot calibrations for GLONASS. With the highly
improved GLONASS constellation that is available today it is possible
to solve for differential receiver antenna offsets between the mean GPS
and the mean GLONASS phase center for multi-GNSS receivers. These
differences are significant and reproducible from day to day.
The newly released igs08.atx model also includes separate receiver
antenna calibration values for the GLONASS frequencies. The estimation
of differential receiver antenna offsets between the two GNSSes is used
to evaluate the system-specific receiver antenna phase center
correction values given in the igs08.atx model. The impact on relevant
parameters (like station coordinates) will be discussed. |
