jpl0756[0-6].sp3 GPS ephemerides for GPS week 756, sp3 format.
______________________________________________________________________________
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
----- ------------ ---------------------
184 jpl07560.sp3 PRN's 17,22
185 jpl07551.sp3 PRN 17
In order to expedite our processing, some days were processed with a well-
distributed subset of the global network consisting of no more than 30 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 755.
WARNING: Data from HARV excluded on day 185 (Jul 4).
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.
