Mean Orbit Repeatability (see table below): 17.9 cm
Beginning this week, we include data from several 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)
DAM2 (Pacoima Dam #2, CA, USA): -2507711.4100 -4638467.8100 3577591.1900
HOPB (Northern CA, USA): -2709010.0500 -4159607.3100 3992196.0500
REYK (Reykjavik, Iceland): 2587386.1455 -1043034.3005 5716566.7749
TIBB (Northern CA, USA): -2704055.4200 -4253077.6200 3895951.5000
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 042-044.
WARNING: PIE1 (not ALGO) used as reference clock on days 045-046.
WARNING: Data from CHIL, KELY, LAMA, MATE, ONSA excluded day 042.
WARNING: Data from CHIL, HART, LAMA, MATE excluded day 043.
WARNING: Data from HART, LAMA, MALI, MATE, NYAL, WLPS excluded day 044.
WARNING: Data from HART, KELY, KOSG, LAMA, MALI, MATE, TABL, WLPS excluded day 045.
WARNING: Data from LAMA, MATE, WLPS excluded day 046.
WARNING: Data from HART, KELY, LAMA excluded day 047.
WARNING: Data from HART, HOPB, KELY, MATE, TIBB excluded day 048.
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)
