Mean Orbit Repeatability (see table below): 17.6 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)
CHAT (Chatham Isl., New Zealand): -4590645.6284 -275465.1076 -4404581.6801
IRKT (Irkutsk, Siberia): -968332.9300 3794424.1200 5018164.8100
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 on days 281 and 283.
WARNING: YELL (not ALGO) used as reference clock on days 282 and 284.
WARNING: Data from CHIL, FAIR, HERS, MAC1, METS, NYAL, SEY1, TMGO, TROM
excluded day 281.
WARNING: Data from CHIL, KELY, MAC1, METS, TMGO, TROM excluded day 282.
WARNING: Data from CHIL, DAV1, IRKT, KOSG, LAMA, TMGO excluded day 283.
WARNING: Data from CICE, DAM1, DAV1, KOKB, KOSG, LAMA, TMGO, WHI1 excluded day 284.
WARNING: Data from DAM1, DAV1, FAIR, KELY, KOSG, LAMA, TMGO excluded day 285.
WARNING: Data from DAM1, JPLM, KELY, METS, NYAL, TMGO, TROM excluded day 286.
WARNING: Data from DAV1, JPLM, KELY, METS, SEY1, TMGO excluded day 287.
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)
