______________________________________________________________________________
This week, we continue our new strategy of adding pseudorange data from several
chosen sites; see jpl07507.sum for details.
Recently, a bug was introduced into our software which affected the orbit
products for week 751 only. We have corrected the problem, and reprocessed the
entire week's data. However, this correction was made AFTER two orbit files
had been posted for public use; namely jpl07510.sp3 and jpl07511.sp3. These
files have been removed from the pub/jpligsac/0751 anonymous ftp directory of
sideshow.jpl.nasa.gov as of Wed Jun 15 13:48:12 PDT 1994. They have also
been removed from the CDDIS as of Thu Jun 16 and are no longer considered
valid. The replacement orbit files are being posted along with this summary
file. We apologize for any inconvenience caused by this replacement.
Please note that because we were attempting to re-analyze the entire week
as expeditiously as possible, we chose to use a 20-station subset of the global
network. The exclusion of other sites is not necessarily indicative of
problems at those stations. The only day that was processed using the full
network of stations was day 155 (Jun 4).
The inclusion of HARV caused an excessive number of outliers in the analyses of
day 155. We have deleted data from this site on this day.
WARNING: Data from NLIB excluded for the entire GPS week 751 (cable deficiency).
WARNING: Data from HARV excluded day 155 (Jun 4).
