Files listed below are available in Unix compressed format and can be retrieved using anonymous ftp to sideshow.jpl.nasa.gov (128.149.70.41), directory pub/jpligsac/0741.

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).
