Median Orbit Repeatability (see table below): 13.0 cm
(excluding deweighted satellites)
According to the file nanu1996.mes obtained from the IGS CBIS, PRN31 was
unusable on days 289 and 290 for maintenance/repositioning. Data from
this satellite did not meet our convergence criteria on either day, and
have been excluded from the analyses of both.
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 ALGO) used as reference clock day 290.
WARNING: FAIR (not ALGO) used as reference clock day 291.
WARNING: Data from PRN10, PRN30 deweighted for the entire GPS week 875.
WARNING: Data from PRN31 excluded days 289 and 290 due to a maneuver.
WARNING: Data from DGAR, SNI1 excluded day 287.
WARNING: Data from DGAR, MEDI excluded day 288.
WARNING: Data from DGAR, ONSA excluded day 289.
WARNING: Data from DGAR, MADR, ONSA excluded day 290.
WARNING: Data from BOGT, DGAR, MDVO excluded day 291.
WARNING: Data from DGAR, UPAD excluded day 292.
WARNING: Data from LPGS, ZWEN excluded day 293.
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)
