JPL ANALYSIS REPORT   GPS-WEEK 0740 (DAYS 72-78, DATES 1994 Mar 13 - Mar 19)

According to IGS Mail Message Nos. 537 and 538, the antenna heights for STJO
and YELL have been modified as of days 073 and 075 (Mar 14, 16) respectively.
These sites have been excluded from our analyses accordingly, pending 
verification of the new information.  

The inclusion of ALGO caused an excessive number of outliers in the analyses
of days 075 and 076 (Mar 16, 17).  Consequently, for these two days, we have
deleted this site from our processing and used FAIR as a reference clock.

According to the file gpsn1.txt obtained from tycho.usno.navy.mil, PRN25 was
scheduled unusable for up to 12 hours beginning at 14:20 UT on day 076 for
repositioning.  We have excluded this satellite from the analysis of this day
and the following day as well.  Also, according to the similarly-obtained
file gpstd.txt, PRN03 has been reportedly unusable since day 058 (Feb 27).
No broadcast ephemeris data is available for this satellite beginning with
day 077 (Mar 18), and it no longer appears in our orbit products beginning
with the corresponding orbit file, jpl07405.sp3.

WARNING: Data from ALGO has been excluded for days 075 and 076. FAIR was used            as the reference clock for these two days only.
WARNING: Data from PRN25 excluded on days 076 and 077 due to a maneuver.
WARNING: PRN03 not available beginning day 077.
