Anti-spoofing was on for days and 267-271 (Sep 24-28). Our analyses of days 269
through 271 were done using our A-S strategy; see jpl07147.sum for details.
Beginning this week, we include data from PRN05/GPS35, which was launched on
Aug 30, 1993 (day 242). Following our usual practices, we have deweighted all
data from this satellite for the entire week of analysis.
According to the file gpsn3.txt obtained from tycho.usno.navy.mil, PRN24/GPS24
was scheduled unusable on day 270 (Sep 27) from 14:45 UT for up to 12 hours for
repositioning. As we use a 30-hr. data interval, we have deweighted data from
this satellite for this day AND the following day (271) as well.
Data from GGAO (Greenbelt, MD, USA) and GRAZ (Graz, Austria) were excluded from
all days except day 271. These data were not well modelled for most of week 716.
WARNING: Data from PRN05/GPS35 have been deweighted for the entire GPSweek 716.
WARNING: Data from PRN24/GPS24 have been deweighted for days 270 and 271 (Sep 27 and 28).
WARNING: Data from GGAO and GRAZ have been excluded for all days of week 716 EXCEPT for day 271 (Sep 28).
