Beginning this week, we include data from PRN09/GPS39, which was launched on
June 26, 1993. Following our usual practices, we have deweighted all data
from this satellite for the entire week of analysis.
Also, beginning July 21, we include data from KIRU (Kiruna, Sweden). The
following nominal coordinates were assumed, and the station location was
estimated (unconstrained) each day:
X = 2251421.0210 m, Y = 862817.1160 m, Z = 5885476.5490 m
Tracking data from MCMU proved to be corrupt for the analysis of day 202
(July 21). Also, the inclusion of data from HART adversely affected our analysis
of day 204. We have therefore not included data from these sites on these days.
These particular sites have also been excluded from the analysis of day 205.
According to IGS Mail Message 305, the antenna at KOKB (Kokee Park) was dis-
placed between July 22, 19:43 and July 23, 02:00 UT. We have subsequently
excluded data from this site for the analyses of these two days, as well as
July 24.
Due to a recent glitch in bodhi operations, data from some sites were included
twice on some days, having the effect of a decrease in the assumed data noise
for such days and sites by sqrt(2). These site-days have been flagged in the
the JPL GROUND STATION INCLUSION TABLE with a caret (^).
WARNING: Data from PRN09/GPS39 have been deweighted for the entire GPSweek 706.
WARNING: Data from HART have been deleted for days 204 and 205 (Jul 23, 24).
WARNING: Data from MCMU have been deleted for days 202 and 205 (Jul 21, 24).
WARNING: Data from KOKB have been deleted for days 203-205 (Jul 22-24), as the antenna was temporarily relocated.
