Median Orbit Repeatability (see table below): 14.0 cm

Data from PRN04 were mismodeled on day 105 and have been excluded accordingly.

Beginning this week, we add two new candidate global stations.  As with other
sites, these stations 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)
CHWK (Chilliwack, Canada)    -2215259.7919   -3543996.9094  4802098.8605
RIOG (Rio Grande, Argentina)  1429907.7808   -3495354.8322 -5122698.7557 

A large clock discontinuity (reset) of about 130 microseconds was detected
for PRN19 at approximately 05:35 on day 106.

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 PRN18 have been excluded the entire GPS week 1005.
WARNING: Data from PRN04 have been excluded day 104.
WARNING: Data from KELY, KIT3, LPGS, URUM excluded day 101.
WARNING: Data from GOUG, KELY, KIT3, LPGS, TIXI, URUM, VESL excluded day 102.
WARNING: Data from GOUG, KELY, KIT3, LPGS, TIXI, URUM, VESL excluded day 103.
WARNING: Data from CRO1, GOUG, HARK, HRAO, IRKT, KELY, KIT3, LPGS, RAMO, SUTH,         TIXI, URUM, VESL excluded day 104.
