______________________________________________________________________________
This week, we continue to exclude all data from PRN12 from our processing.
Additionally, because of interactions with recent changes in software
associated with the new GPS attitude model, we have excluded several satellites
from our sp3 files as follows:
DAY sp3 FILE Excluded Satellites
----- ------------ ---------------------

178 jpl07551.sp3 PRN's 15,17,31

183 jpl07556.sp3 PRN's 15,17,22,31
Day 178 (Jun 27) was processed prior to our updating of IERS Bulletin B nominal
values. This is manifested in the apparent discontinuity in UT1R-UTC on this
day.
In order to expedite our processing, some days were processed with a well-
distributed subset of the global network consisting of no more than 25 sites.
The exclusion of other sites is not necessarily indicative of problems at
those stations.
WARNING: Data from PRN12 excluded for the entire GPS week 754.
In the following table, UT1R-UTC are the assumed nominal values from IERS
Bulletin-B predicts; estimated LODR values are also included. See IGS Mail
Message 97 for details.
