Median Orbit Repeatability (see table below): 15.0 cm
Apparent mismodeling of recently-launched PRN10 seems to have had an adverse
affect on LODR estimates over the past few weeks. Beginning this week,
we have elected to indefinitely exclude data from this satellite from our
analyses. Some days in week 870 were processed prior to this decision, hence
the inclusion of PRN10 on these days. PRN10 has been excluded, however, from
all final sp3 products for this week.
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: PIE1 (not ALGO) used as reference clock days 257 and 258.
WARNING: Data from PRN10 excluded days 254, 255, and 258.
WARNING: Data from HKLO excluded day 252.
WARNING: Data from DGAR excluded day 253.
WARNING: Data from DGAR, WUHN excluded day 254.
WARNING: Data from DGAR, POTM, WUHN, ZWEN excluded day 255.
WARNING: Data from DGAR, EISL, NYAL, ZWEN excluded day 256.
WARNING: Data from CLAR, DGAR excluded day 257.
WARNING: Data from DGAR, KRAK, WINT, WLPS excluded day 258.
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)
