Median Orbit Repeatability (see table below): 6.0 cm
This week, we add two new candidate global stations. As with other sites,
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)
OBE2 (Oberpfaffenhofen, Germany) 4186558.4962 835027.3904 4723759.4847
ULAB (Ulaanbataar, Mongolia) -1257408.5014 4099404.4839 4707992.7159
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 PRN15 and PRN19 excluded the entire GPS week 1127.
WARNING: Data from PRN20 excluded day 225.
WARNING: Data from PRN17 excluded days 227-230.
WARNING: Data from PRN21 excluded day 230.
WARNING: Data from ANKR, GUAM, HILO, HOLP, IRKT, LBCH, WLSN, WTZT excluded day 224.
WARNING: Data from HILO, HOLP, ISTA, KELY, LBCH, TORP, WLSN excluded day 225.
WARNING: Data from GOUG, HILO, HOLP, KOUR, LBCH, MEDI, NKLG, SSIA, TORP, YAR1 excluded day 226.
WARNING: Data from BJFS, HILO, HOLP, LBCH, TORP, WLSN, YAR1 excluded day 227.
WARNING: Data from HILO, HOLP, JAB1, JAMA, LBCH, RIOG, WLSN, YAR1 excluded day 228.
WARNING: Data from HILO, HOLP, JAB1, LBCH, WES2, WLSN, YAR1 excluded day 229.
WARNING: Data from DRAG, HILO, JAB1, LBCH, WLSN excluded day 230.
