Mean Orbit Repeatability (see table below): 20.6 cm
Beginning this week, we include data from two new stations. As with most
stations, these sites are given the opportunity to participate in the orbit
and clock solution as the global site distribution varies. The following
nominal coordinates were assumed:
X (m) Y (m) Z (m)
AUCK (New Zealand): -5105691.8339 461570.4541 -3782192.8866
KELY (Kellyville, Greenland): 1575568.2433 -1941836.5508 5848072.0110
Although used in our processing, we have elected to remove results for PRN17
from the orbit solution for day 276 (jpl08212.sp3) due to possible mismodeling.
Solutions for day 281 were not available at the time of the compilation of
this report, hence the single-digit precision in the orbit repeatability table
below.
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 AREQ, DAV1, HBRK, HKLO, METS, OHIG, UPAD, VCIO, VNDP, WETT, WSMN excluded day 274.
WARNING: Data from AREQ, CHIL, DAV1, HERS, KIRU, MATE, OHIG, SANT, WETT excluded day 275.
WARNING: Data from AREQ, CHIL, GRAZ, HERS, KIRU, MAS1, OHIG excluded day 276. NLIB (not ALGO) used as reference clock this day.
WARNING: Data from FAIR, HERS, KIRU, TMGO, TROM excluded day 277.
WARNING: Data from FAIR, SANT, TMGO excluded day 278. YELL used as reference clock this day.
WARNING: Data from DAV1, KELY, SEY1, TMGO excluded day 279. NLIB used as reference clock this day.
WARNING: Data from FAIR, HERS, MAC1, NYAL, SEY1, TMGO, TROM excluded day 280. NLIB used as reference clock this day.
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)
