BKG Analysis Report for r1991 (21MAR23XA) 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: NYALE13S halted (13:57-15:21 UT) for pointing and calibration test also shows low fringe amplitude in the S-band channel which resulted in then unused observations. SEJONG has no signal in several S-band channels so that observations were not recovered. WETTZ13N-WETTZELL shows numerous sub-ambiguities due to the removed channel in S-band.
