JPL ANALYSIS REPORT   GPS-WEEK 0733 (DAYS 23-29, DATES 1994 Jan 23 - Jan 29 )

Pasadena, CA  91109.

Files listed below are available in Unix compressed format and can be
retrieved using anonymous ftp to sideshow.jpl.nasa.gov (128.149.70.41),
directory pub/jpligsac/0733.  These files have also been sent to the CDDIS.

According to the file gpsn1.txt obtained from tycho.usno.navy.mil, PRN24/GPS24
was scheduled unusable for an indefinite period beginning at 17:45 on day 023.
This satellite was excluded from the analysis of the FOLLOWING day.  Its
absence from our orbit tables for the remainder of the week is explained by the 
atypically low number of measurements processed from this transmitter on these
days.

As mentioned in jpl07297.sum, we are now using ITRF92 station coordinates in
our analyses.  We have since discovered that the headers in several of our
sp3 files erroneously indicated that ITRF91 was used.  These files have been
corrected and resubmitted to the CDDIS (no orbit information is affected).
The dates/files affected by this modification are listed below:

                  jpl0728[1-5].sp3 (Monday - Friday only)
                  jpl0729[0-6].sp3 (entire week)
                  jpl0730[0-6].sp3 (entire week)
                  jpl0731[0-6].sp3 (entire week)
                  jpl0732[0-6].sp3 (entire week)
     
Some stations (for example, Kiruna) are currently excluded only because of an
arbitrary software limit on number of estimated parameters, which will soon be
increased.

WARNING: Data from PRN24/GPS24 were exlcuded on day 024.
