Median Orbit Repeatability (see table below): 11.0 cm
We continue to deweight data from PRN13; this satellite does not appear in
any of our orbit products for this week. Also, data from PRN22 did not meet
our initial orbit convergence criteria on days 267 and 268, and have been
excluded from these days' analyses accordingly. Lastly, PRN29 exhibits
atypically high orbit repeatability on day 270. Although used in this day's
analysis, we have elected to remove it from the corresponding orbit product,
jpl09246.sp3.
A clock reset (large discontinuity) of about 83 microseconds was detected for
PRN30 at approximately 01:05 UT on day 266.
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 264, 265, and 267-270.
WARNING: Data from PRN13 deweighted the entire GPS week 924.
WARNING: Data from PRN22 excluded days 267 and 268.
WARNING: Data from ANKR, JOZE, SNI1, TAIW excluded day 264.
WARNING: Data from ANKR, CAT1, CSN1, TAIW excluded day 265.
WARNING: Data from ANKR, CSN1 excluded day 266.
WARNING: Data from ANKR, CSN1, KELY excluded day 267.
WARNING: Data from ANKR, AZU1, SNI1 excluded day 268.
WARNING: Data from KELY, ROCK, SNI1, TAIW, UCLP excluded day 269.
WARNING: Data from KELY, SNI1, TAIW excluded day 270.
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)
