Median Orbit Repeatability (see table below): 11.0 cm
We continue to deweight data from PRN13, and we have excluded its solution
from all of the orbit products for this week. Additionally, PRN29 and PRN03
exhibited atypically high overlaps on days 278 and 283 respectively. We have
chosen to remove these satellites from the corresponding day's analysis.
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 PRN29, ANKR, CLAR, TAHI excluded day 278.
WARNING: Data from ANKR excluded day 279.
WARNING: Data from ROCK, SANT, SCH2, SNI1 excluded day 281.
WARNING: Data from BLYT, IISC, LONG excluded day 282.
WARNING: Data from PRN03, MEDI, WTZR, ZWEN excluded day 283.
WARNING: Data from ALBH excluded day 284.
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)
