Median Orbit Repeatability (see table below): 11.0 cm
Begining day 329, we include data from PRN08, a new Block IIA satellite
launched on day 310. Adhering to our usual practices, we have chosen to
heavily deweight data from this new satellite for all days used. No solutions
for this satellite are included in our orbit products for week 933.
Original analyses indicated that data from PRN14 appear mismodeled on days
327 and 330-333. Although used with normal weighting in the analyses of days
327, 330, and 331, we have chosen to remove this satellite's solution from the
corresponding orbit products (jpl09330.sp3, jpl09333.sp3, jpl09334.sp3).
Additionally we have reanalyzed days 332 and 333, and elected to deweight data
from this satellite for these two days only. Consequently, this satellite
does not appear in the orbit products for these days either.
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 day 327.
WARNING: Data from PRN14 deweighted days 332 and 333.
WARNING: Data from MAS1, SNI1 excluded day 327.
WARNING: Data from SANT, SOFI, THU1 excluded day 328.
WARNING: Data from KSTU, PIN2 excluded day 329.
WARNING: Data from SANT, SFER excluded day 330.
WARNING: Data from LAMA, SFER excluded day 331.
WARNING: Data from AOA1, CICE, CIT1, CSN1, KSTU, METS, OAT2, SELE, SOL1 excluded day 332.
WARNING: Data from NICO excluded day 333.
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)
