JPL ANALYSIS REPORT GPS-WEEK 0741 (DAYS 79-85, DATES 1994 Mar 20 - Mar 26)
******************************************************************************
Submitted by the JPL IGS/FLINN Analysis Team:

Pasadena, CA 91109.

______________________________________________________________________________
According to the file constell.gps obtained from the IGS CBIS, PRN06/GPS36
was launched on day 069 (Mar 10). Tracking data for this new satellite have
appeared at some sites as early as day 079. However, no ephemeris data are
presently available; the aforementioned file indicates usability as of day 087
(Mar 28). All tracking data for this satellite have been removed from our
analyses for the entire week.
A few sites in particular caused excessive numbers of outliers in our analyses
this week. These are NLIB, HARV, and ONSA on days 079, 080, and 083 (Mar 20,
21, 24) respectively. Data from these sites have been deleted from our
processing on the appropriate days.
In our last report (jpl07407.sum), we mentioned that PRN03 was no longer
available. In retrospect, we find that this was a temporary condition; orbit
solutions for this satellite have been included again beginning with day 082,
(Mar 23) in the jpl07413.sp3 file.
WARNING: PRN06 launched day 069 (Mar 10); no data included for GPS week 741.
WARNING: Data from NLIB have been excluded for day 079 (Mar 20).
WARNING: Data from HARV have been excluded for day 080 (Mar 21).
WARNING: Data from ONSA have been excluded for day 083 (Mar 24).
