BKG Analysis Report for i20286 (20OCT12XU)
       This report is a contributed analysis report that does not correspond to 
       the database maintained by the IVS Data Centers for this session. 
   (Analyzed by Anastasiia Girdiuk, Federal Agency for Cartography and Geodesy (BKG),
    Spoolfile source: interactive nuSolve analysis.) 

Problems: subambiguitites in S-band is 50 ns not 100 ns, as follows 6 observations had to be removed.

Number of observations rejected during correlation:    0

Number of observations not usable by the software:    13
