JPL ANALYSIS REPORT   GPS-WEEK 0744 (DAYS 100-106, DATES 1994 Apr 10 - Apr 16)

Pasadena, CA  91109.

______________________________________________________________________________

According to the file nanu1994.mes obtained from the IGS CBIS, PRN06/GPS36
was scheduled unusable from day 099 (Apr 9) 14:56 UT to day 102 (Apr 12)
16:00 UT, and from day 106 (Apr 16) 14:08 UT to day 108 (Apr 18) 15:40 UT for
repositioning.  We have included data from this satellite for days 103-105
(Apr 13-15) only.

Additionally, IGS Mail Message 572 indicates that PRN03/GPS11 is expected to be
permanently unsuable as of day 103.  This satellite no longer appears in our
solutions beginning with jpl07443.sp3, the corresponding orbit file for this
day.

According to IGS Mail Message 568, the antenna at ALBH was changed on day 104
(Apr 14).  Also, the inclusion of data from NLIB caused an excessive number of
outliers in the analysis of day 106.  We have deleted these sites from our
processing on the corresponding days.

WARNING: Data from PRN06 have been excluded for days 099-102 and 106 due to              maneuvering. 
WARNING: Data from ALBH have been excluded for day 104 due to an antenna change.
WARNING: Data from NLIB have been excluded for day 106.
WARNING: No data from PRN03 as of day 103; satellite out of service.
WARNING: Little data from PRN13 on day 101.
