It should be mentioned that R06 data is already considered in the GNSS POD processes at CODE (since D088). Until now, no Z18 receiver was able to provide data with respect to this particular GLONASS satellite. R06 is expected to be marked unusable over a longer period of time (of possibly several months). Best regards, Stefan Schaer
