STRATEGY UPDATE
---------------
Beginning day 336 (December 2, 2001), JPL ultra-rapid, rapid, and final
products submitted to the IGS make use of the IGS00 terrestrial reference
frame. The station monument coordinates and velocities of the designated
54 "core" stations are taken from:
ftp://macs.geod.emr.ca/pub/requests/sinex/rfwg/IGS01P37_RS54.snx.Z
and antenna heights from ftp://igscb/igscb/station/general/igs.snx.
(Antenna reference point to L1 and L2 phase centers are from
ftp://igscb/igscb/station/general/igs_01.pcv.)
The jpl.acn file at the IGS CBIS has been updated to reflect the switch to
the new reference frame. Please note that orbits, Earth orientation, SINEX
station coordinates, and daily transformation files submitted to the IGS are
still all free-network solutions, but are now aligned with IGS00.
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 1143.
WARNING: Data from PRN29 excluded day 336.
WARNING: Data from PRN04 excluded day 337.
WARNING: Data from CAGS, DARW, DUBR, GUAM, LBCH, LHAS, LHUE, PETP, WUHN, YAR1 excluded day 336.
WARNING: Data from DUBR, GUAM, IRKT, LAE1, LBCH, LHUE, PETP, SFDM, SOFI, SSIA, WES2, YEBE excluded day 337.
WARNING: Data from HILO, HOLM, IRKT, LBCH, LHUE, PIMO, RIOG, SLOR, SSIA, WES2 excluded day 338.
WARNING: Data from BJFS, HILO, IRKT, JAMA, LBCH, MSKU, PIMO, WES2, YAR1 excluded day 339.
WARNING: Data from CHUM, FORT, GALA, HILO, LBCH, MATE, PIMO, SSIA, WES2 excluded day 340.
WARNING: Data from LBCH, PIMO, UNSA, WES2, WTZA excluded day 341.
WARNING: Data from WES2, WTZA excluded day 342.
