Median Orbit Repeatability (see table below): 6.0 cm

This week, we add one new candidate global station.  As with other sites,
this site 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)
FALE (Faleolo, Samoa)         -6134111.9619    -862145.0929   -1514974.6243

A frequency shift from about -21 ps/s to +88 ps/s was detected for PRN17
at approximately 20:30 on day 155.

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 excluded the entire GPS week 1117.
WARNING: Data from PRN03, PRN29, PRN30 excluded day 160.
WARNING: Data from ESTI, GENO, HNPT, LBCH, MALI, PETP, REYK, SFDM, SFER, WLSN,           YAR1, ZWEN excluded day 154.
WARNING: Data from INEG, LBCH, MAUI, NVSK, PETP, SFER, WLSN, ZWEN excluded day           155.
WARNING: Data from LBCH, LONG, MAUI, PETP, SANT, SFER, WLSN, YAR1 excluded day           156.
WARNING: Data from CASA, LBCH, PETP, SFER, WLSN excluded day 157.
WARNING: Data from AREQ, LBCH, PETP, SFER, TEGU, WLSN excluded day 158.
WARNING: Data from COCO, KELY, KOKB, LBCH, MAS1, NVSK, PETP, SFER, USNA, USNO,           WLSN excluded day 159.
