Mean Orbit Repeatability (see table below): 23.5 cm
(excluding PRN03 on all days, and PRN16 on days 103 and 104.)
Data from PRN01 did not meet our initial convergence criteria on days 103 and
104, and have been consequently excluded from the analyses of these two days.
Beginning this week, our processing has included data from the newly-launched
satellite PRN03. As the orbit repeatability table shows, this satellite was
not well modeled. We have therefore chosen not to include this satellite
in our sp3 orbit products this week.
Lastly, according to the file nanu1996.mes obtained from the IGS CBIS, PRN16
was unusable on days 103 through 106. Although this satellite was used in
our analyses on days 103 and 104, we are excluding this satellite from our sp3
files for these two days because of difficulty modeling the attittude due
to the failure of its second reaction wheel.
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 GUAM, IISC, IRKT, KELY, LONG, MATE, SHAO, TAEJ, TAIW excluded day 098.
WARNING: Data from GUAM, IISC, IRKT, KELY, MATE, POL2, SFER, SHAO, TAEJ, TAIW, ZIMM excluded day 099.
WARNING: Data from ANKR, CHAB, GUAM, IISC, IRKT, KIT3, MAS1, MATE, POL2, SFER, SHAO, TAEJ, TAIW, ZIMM excluded day 100.
WARNING: Data from MATE, SFER, TABL excluded day 101.
WARNING: Data from MATE, SFER excluded day 102.
WARNING: Data from FAIR, KELY, MATE, TIBB, TROM, UPAD, USC1 excluded day 103.
WARNING: Data from DAV1, KOKB, MALI, MATE, SFER, TABL, TROM, USC1 excluded day 104.
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)
