Median Orbit Repeatability (see table below): 8.0 cm
This week, we add a new candidate global station. As with other sites,
this site is 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)
ORID (Ohrid, Macedonia) 4498451.8655 1708266.9432 4173591.8938
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: PIE1 (not USNO) used as reference clock days 261, 262, 266, and 267.
WARNING: NRC1 (not USNO) used as reference clock days 263 and 265.
WARNING: Data from PRN15 and PRN28 excluded the entire GPS week 1080.
WARNING: Data from GUAT, MANA, PETP, WTZT excluded day 261.
WARNING: Data from KELY, LBCH, NTUS, PETP, RAMO, VNDP, WTZT excluded day 262.
WARNING: Data from LBCH, NTUS, PETP, USNO, WTZT excluded day 263.
WARNING: Data from MANA, PETP, YAKZ excluded day 264.
WARNING: Data from CHIL, NICO, PETP, TABL, UNSA excluded day 265.
WARNING: Data from KUNM, LBCH, NTUS, PETP, SANT, WTZT excluded day 266.
WARNING: Data from PETP, WTZT excluded day 267.
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)
