JPL ANALYSIS REPORT   GPS-WEEK 0732 (DAYS 16-22, DATES 16-1-94 TO 22-1-94)

According to the file gpsn1.txt obtained from tycho.usno.navy.mil, PRN17/GPS17
was scheduled unusable on day 020 from 17:15 UT for up to 12 hours for
repositioning.  We have excluded data from this satellite on this day and the
following day (021) as well.

We have refined our estimate of JPL's position following the Northridge
Earthquake of 12:31 UT on January 17.  Using the receiver at Goldstone as a
reference (expected motion of Goldstone following this event is much less than
1 mm; the removal of this station as a fixed site, in retrospect, is not
necessary), and data from Jan 12 through Jan 22, we estimate motion as follows:

                          north    -5.7 +- 1.4 mm
                          east      7.4 +- 1.0 mm
                          vertical -2.6 +- 3.5 mm

These values are consistent with our earlier result (IGS mail 455) and
those from SIO (Bock et al., IGS mail 457).

WARNING: Because of the Northridge Earthquake (day 017), GOLD was not used as            a fiducial (constrained) site for the entire GPS week 732.
WARNING: Due to the maneuver of PRN17/GPS17, data from this satellite have been          deleted for days 020 and 021.
