Median Orbit Repeatability (see table below): 8.0 cm
According to the file ftp://tycho.usno.navy.mil/pub/gps/gpsnanu.2002, PRN24
was unusable from day 2001.365 through day 2002.007. This satellite has
been excluded from our analyses according to the warnings below.
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)
BREW (Brewster, WA, USA) -2112007.1251 -3705351.8830 4726827.2306
MANZ (Manzanillo, Colima, Mexico) 801913.3814 -6237949.7244 1058473.5355
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 1147.
WARNING: Data from PRN26 excluded days 2001.365 and 2002.001.
WARNING: Data from PRN24 excluded days 2002.001-003 and 2002.005.
WARNING: Data from PRN14 excluded day 2002.005.
WARNING: Data from DRAG, LBCH, RIOG, RIOP, SSIA, WTZA excluded day 2001.364.
WARNING: Data from DUBR, LBCH, LHUE, PIMO, SOL1, WTZA excluded day 2001.365.
WARNING: Data from DUBR, GODE, HOLB, HOLM, LBCH, PIMO excluded day 2002.001.
WARNING: Data from CORD, DARW, DUBR, GODE, GRAZ, LBCH, MAD2, PIMO excluded day 2002.002.
WARNING: Data from DARW, GODE, IISC, LBCH, PIMO, RABT excluded day 2002.003.
WARNING: Data from DARW, GODE, LBCH, LHUE, MALI, WTZA excluded day 2002.004.
WARNING: Data from LBCH, PIMO, SLOR, WTZA excluded day 2002.005.
