Median Orbit Repeatability (see table below): 9.0 cm
At the 1999 IGS Analysis Center Workshop hosted by the Scripps Institute of
Oceanography (SIO), it was recommended that all AC products make use of the
new receiver and antenna names (see IGS Mail Message 2281) as of day 185
(week 1017). Starting last week (1016), JPL product files comply with this
recommendation.
We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae, namely: BAKO BZRG GOPE HOFN INEG JOZE MATH MDVO PENC WTZT.
According to the file nanu1999.mes obtained from the IGS CBIS, PRN13 was
unusable days 188 through 193. No data from this satellite were available
days 189 through 191 this week.
Data from PRN06, PRN16, and PRN25 were mismodeled on day 191 and have been
excluded accordingly.
Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated. (For
geographical reasons, they may not have been used in any case.)
WARNING: PIE1 (not USNO) used as reference clock days 185 and 187-190.
WARNING: GOL2 (not USNO) used as reference clock day 186.
WARNING: Data from COCO excluded day 185.
WARNING: Data from KOUR excluded day 186.
WARNING: Data from KIT3 excluded day 187.
WARNING: Data from ALGO, AMC2, IISC, KIT3, LHAS excluded day 188.
WARNING: Data from AMC2, AOML, BRMU, IISC, USNO excluded day 189.
WARNING: Data from KOKB, THU1 excluded day 190.
WARNING: Data from PRN06, PRN16, PRN25, HARK, KOKB, KOSG, MAG0, RIOG, SFER excluded day 191.
In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column. See IGS Report No. 1498 (jpl07827.sum)
