Median Orbit Repeatability (see table below): 20.0 cm
According to the file nanu1996.mes obtained from the IGS CBIS, PRN01 was
unusable on days 229 through 235. Although used in each day's analysis,
we have chosen to exclude this satellite from our sp3 orbit products for
days 232 and 233 (jpl08671.sp3 and jpl08672.sp3).
Data from PRN10 continues to appear mismodeled in our processing. Although
used in each day's analysis, we have chosen to excluded this satellite from
our sp3 orbit prodcucts for the entire week (jpl0867[0-6].sp3).
Also, PRN16 was declared unusable during various periods on days 233
through 235 for mantainence/repositioning. Inclusion of data from this
satellite on previous days resulted in many outliers in our solutions, and
therefore, these days were reanalyzed excluding this satellite. Data from
this satellite is included normally beginning with day 235.
Lastly, PRN28 was declared unusuable on day 236 for maintenance/repositioning.
Navigation data from this satellite did not meet our convervgence criteria
this nor the following day (237), and were subsequently excluded from both
days analyses.
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 ALGO) used as reference clock on days 234 and 236.
WARNING: FAIR (not ALGO) used as reference clock on days 235.
WARNING: Data from PRN16 excluded on days 231-234 due to maneuvers.
WARNING: Data from PRN28 excluded on days 236 and 237 due to a maneuver.
WARNING: Data from DGAR, KOKB, ONSA, POTM, STJO, WETT excluded day 231.
WARNING: Data from BRU1, DGAR, ENG1, FMC2, FORT, ONSA, SHK1, STL3 excluded
day 232.
WARNING: Data from CAS1, CMBB, DAV1, DGAR, FORT, ONSA, POTM, TAIW excluded day 233.
WARNING: Data from CMBB, DAM2, DGAR, SNI1 excluded day 234.
WARNING: Data from CMBB, DAM2, SNI1 excluded day 235.
WARNING: Data from CHIL, DAM2, DGAR, GRAZ, LPGS excluded day 236.
WARNING: Data from DGAR, STJO excluded day 237.
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)
