According to the file nanu1994.mes obtained from the IGS CBIS, PRN04/GPS34
was scheduled unusable for up to 12 hours beginning at 02:00 UT on day 087
(Mar 28) for repositioning.  Data from this satellite have been deleted for
this day's processing and the following day as well.

The inclusion of data from KOKB caused an excessive number of outliers in the
analyses of days 088 and 089 (Mar 29, 30).  Data from NLIB had a similar
effect on the analysis of day 092 (Apr 02).  Lastly, according to the updated
information in areq0394.log (IGS CBIS, see IGS Mail Message #550), the GPS
antenna at AREQ was relocated on day 088.  We have deleted these sites from our
processing on the appropriate days.

No data from the newly-launched PRN06 has been included in this week's
analyses.

WARNING: PRN06 launched day 069; no data included for GPS week 742.
WARNING: Data from PRN04 excluded on days 087 and 088 due to a maneuver.
WARNING: Data from KOKB have been excluded for days 088 and 089.
WARNING: Data from AREQ have been excluded for day 088 (antenna relocation).
WARNING: Data from NLIB have been excluded for day 092.
