jpl08477.erp Earth rotation parameters for GPS week 847.
jpl08477.snx Ground station coordinates for GPS week 847, SINEX format.
jpl0847[0-6].sp3 GPS ephemerides for GPS week 847, sp3 format.

Mean Orbit Repeatability (see table below): 17.5 cm
Beginning day 091, we use TID2 and WTZR as fixed sites instead of TIDB and
WETB respectively. As both of the new sites utilize Turbo-Rogue receivers, we
analyze all pseudorange from both; these data were excluded when the older,
regular Rogues were used. Since TID2 operates with the same Deep Space Network
GPS antenna as TIDB, the constrained nominal coordinates have not changed.
Nominal coordinates for WTZR, however, were obtained using the site tie
information found in the file wtzr0196.log obtained from the IGS CBIS; note
that they are slightly different from those mentioned in our AC summary
jpl08447.sum (IGS Report No. 2518):
X (m) Y (m) Z (m)
4075580.6976 931853.6432 4801568.0256
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: ONSA (not ALGO) used as reference clock on day 094.
WARNING: Data from NOTO, NYAL, TABL, ZIMM, ZWEN excluded day 091.
WARNING: Data from FAI2, FORT, KELY, MAS1, TIBB, ZIMM, ZWEN excluded day 092.
WARNING: Data from FAI2, MATE, ZIMM excluded day 093.
WARNING: Data from DAM1, HOLC, MATE, TRAK excluded day 094.
WARNING: Data from HOLC, KELY, MADR, MAS1, MATE, TROM, ZIMM, ZWEN excluded day 095.
WARNING: Data from LONG, MAS1, MATE, ZIMM excluded day 096.
WARNING: Data from CHIL, MATE, TABL, ZIMM excluded day 097.
In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column. See IGS Report No. 1498 (jpl07827.sum)
