Median Orbit Repeatability (see table below): 8.0 cm
This week, we add three new candidate global stations. As with other sites,
these sites 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)
NRIL (Norilsk, Russian Federation) 64537.2902 2253782.9180 5946363.6340
RBAY (Richardsbay, S. Africa) 4739765.9403 2970758.2793 -3054077.8671
YEBE (Yebes, Spain) 4848724.8079 -261632.2914 4123094.1106
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: NRC1 (not USNO) used as reference clock days 282 and 288.
WARNING: ALGO (not USNO) used as reference clock days 286 and 287.
WARNING: Data from PRN15 and PRN28 excluded the entire GPS week 1083.
WARNING: Data from PRN13 excluded days 284 and 285.
WARNING: Data from PRN11 excluded days 286 and 287.
WARNING: Data from GUAT, JAB1, KELY, PETP, RIOG, WTZT excluded day 282.
WARNING: Data from EPRT, MEDI, NICO, NTUS, PETP, WTZT excluded day 283.
WARNING: Data from KELY, LBCH, NICO, NTUS, OAT2, PETP, UNSA, WTZT excluded day
284.
WARNING: Data from DGAR, GUAT, JAB1, LBCH, MALI, PETP, UNSA excluded day 285.
WARNING: Data from GUAT, JAB1, LBCH, PETP, WTZT excluded day 286.
WARNING: Data from DRAG, GUAT, JAB1, MALI, PETP, WTZT excluded day 287.
WARNING: Data from ESTI, GUAT, LBCH, PETP, WTZT excluded day 288.
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)
