Median Orbit Repeatability (see table below): 6.0 cm

STRATEGY UPDATE
---------------
Beginning day 097 (April 7, 2002), the number of ground stations used 
to produce the JPL final products submitted to the IGS was increased
from 42 to 60 ground stations.  Please note that orbits, Earth orientation,
SINEX station coordinates, and daily transformation files submitted to the
IGS are still all free-network solutions, and continue to be aligned 
with IGS00.

A clock discontinuity (reset) of about 42 microseconds was detected for
PRN31 at approximately 15:00 on day 105.

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 1162.
WARNING: Data from PRN24 was excluded day 110.
WARNING: Data from BRUS, HILO, HNLC, KUNM, LHUE, MAUI, PETP, SEY1,                       SPK1 excluded day 104.
WARNING: Data from BJFS, BRUS, DARW, HNLC, KELY, LAE1, LHUE, MANA, MAUI,                 SLOR, SPK1, ULAB excluded day 105.
WARNING: Data from BRUS, DARW, EISL, HNLC, LAE1, LHUE, MANA, MAUI, POLV,                 SLOR, SPK1, ULAB excluded day 106.
WARNING: Data from CAGS, DARW, ESTI, LAE1, MANA, MANZ, SLOR excluded day 107.
WARNING: Data from DARW, EISL, LAE1, MANZ, NRIL excluded day 108.
WARNING: Data from DARW, EISL, MAUI, PETP, WUHN excluded day 109.
WARNING: Data from AOML, DARW, EDPP, MAUI, MSKU, ORID, PETP, PTBB, THU1,                 WUHN excluded day 110.
