Median Orbit Repeatability (see table below): 14.0 cm
Data from PRN19 did not meet our initial orbit convergence criteria on days
108 and 109. This satellite has been excluded from these days analyses
accordingly.
Data from PRN28 appeared to be mismodeled in our processing; we have chosen to
exclude it from our analyses for days 105-109. Although used in the analyses
of days 103 and 104, the solution for this satellite has been removed from the
corresponding orbit products (jpl09010.sp3, jpl09011.sp3).
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: NLIB (not ALGO) used as reference clock days 103-105.
WARNING: Data from PRN28 excluded days 105-109.
WARNING: Data from PRN19 excluded days 108 and 109.
WARNING: Data from USNA excluded day 103.
WARNING: Data from HVLK, WTZR excluded day 104.
WARNING: Data from CAS1, EBRE, KELY, MAC1, MONP, NYAL, WTZR excluded day 105.
WARNING: Data from LEEP, MONP, NYAL, SANT, WTZR excluded day 107.
WARNING: Data from BOGT, SNI1, WTZR excluded day 108.
WARNING: Data from ONSA, SANT, WTZR excluded day 109.
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)
