______________________________________________________________________________
Median Orbit Repeatability (see table below): 16.0 cm
(excluding deweighted satellites).
Although we have been including data from PRN10 normally since GPS week
878, this satellite still seems to be mismodeled. We have seen an adverse
effect on polar motion results when using these data regularly, and have
chosen to again deweight them indefinitely beginning day 325. As a
consequence, solutions for PRN10 do not appear in the corresponding orbit
products, jpl0880[3-6].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 323-325.
WARNING: PIE1 (not ALGO) used as reference clock days 326-328.
WARNING: Data from PRN10 deweighted days 325-328.
WARNING: Data from CHIL, EISL, WSMN excluded day 322.
WARNING: Data from DHLG, EISL, STL3 excluded day 323.
WARNING: Data from CSN1, DHLG, FORT excluded day 324.
WARNING: Data from FORT, TROM excluded day 325.
WARNING: Data from BRAZ, FORT excluded day 326.
WARNING: Data from BRAZ excluded day 327.
WARNING: Data from BRAZ, CMBB, KRAK excluded day 328.
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)
