Median Orbit Repeatability (see table below): 13.0 cm
(excluding deweighted satellites)
Data from PRN10 and PRN30 continue to appear mismodeled; we have deweighted
data from these two satellites for most or all of this week. (Due to
implementation time and some initial software anomalies, data from PRN10
were used with normal weighting on day 280. We have chosen to remove this
satellite from the corresponding orbit product jpl08740.sp3.)
According to the file nanu1996.mes obtained from the IGS CBIS, PRN21 was
unusable on days 281 through 284 for maintenance (no maneuver). Data from
this satellite were used in our analyses of these days.
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: Data from PRN10 deweighted days 281-286.
WARNING: Data from PRN30 deweighted for the entire GPS week 874.
WARNING: Data from BRAN, CSN1, GOLD, SNI1, TIDB excluded day 280.
WARNING: Data from CSN1, DGAR, FMC2, GOLD, HBRK, TIDB excluded day 281.
WARNING: Data from DGAR, FMC2 excluded day 282.
WARNING: Data from CHIL, CRFP, DGAR excluded day 283.
WARNING: Data from DGAR, KRAK, NOTO, TROM excluded day 284.
WARNING: Data from DGAR, KRAK, LPGS, NOTO, POTM excluded day 285.
WARNING: Data from KELY, MEDI, NOTO excluded day 286.
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)
