Median Orbit Repeatability (see table below): 8.0 cm
A clock discontinuity (reset) of about 38 microseconds was detected for
PRN27 at approximately 17:30 on day 298.
This week, we add one new candidate global station. As with other sites,
this sites is 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)
LHUE (Lihue, Kauai, HI, USA) -5536611.3236 -2087777.5398 2372844.9544
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 PRN17 excluded the entire GPS week 1137.
WARNING: Data from CAGL, DRAG, FORT, GOL2, KOUR, LBCH, RIOP, TORP, WLSN excluded day 294.
WARNING: Data from AMMN, DRAG, FORT, KOUR, LBCH, MSKU, RIOP, THU1, TORP, USNA, WUHN excluded day 295.
WARNING: Data from BRMU, DRAG, FORT, GOLD, HILO, KUNM, LBCH, RIOP, THU1, USNA, WLSN, WUHN, YAR1 excluded day 296.
WARNING: Data from CIT1, DRAG, FORT, HILO, JAB1, KARR, LBCH, SOL1, THU1, TLSE, WLSN, WUHN, YAR1, YEBE excluded day 297.
WARNING: Data from CIT1, FORT, HILO, JAB1, LBCH, MALI, TEGU, TLSE, WLSN excluded day 298.
WARNING: Data from CIT1, DRAG, FORT, HNPT, JAB1, LBCH, SLOR, TLSE excluded day 299.
WARNING: Data from FORT, HILO, HNLC, JAB1, LBCH, WLSN excluded day 300.
