been sent to the CDDIS.

Median Orbit Repeatability (see table below): 7.0 cm
According to the file nanu1998.mes obtained from the IGS CBIS, PRN04 was
unusable on day 161. Data from this satellite did not meet our initial
orbit convergence criteria this day, and have been excluded accordingly.
According to IGS Mail No. 1919, the receiver at TAHI (Papeete, Tahiti) was
moved to a new location and renamed THTI on day 110 (GPS week 954, day 1;
98apr20). Although data from the new station were used in the analyses of
weeks 959 and 960, statistics reported for the site in our Analysis Center
weekly reports and SINEX files (jpl09597.sum, jpl09597.snx, jpl09607.sum,
jpl09607.snx) were incorrectly labeled "TAHI". The SINEX files have been
corrected, and resubmitted to the CDDIS and the IGSCB. As usual, THTI is
given the opportunity to participate in the orbit and clock solution as the
global site distribution varies. The following nominal coordinates are
assumed for the weeks indicated:
X (m) Y (m) Z (m)
THTI: -5245195.2928 -3080472.2325 -1912825.4175 (wks 959, 960)
THTI: -5246568.8260 -3076989.4730 -1913777.5080 (begin wk 961)
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 IISC excluded day 158.
WARNING: Data from NYAL excluded day 160.
WARNING: Data from PRN04 excluded day 161.
WARNING: Data from KSTU excluded day 162.
WARNING: Data from KSTU excluded day 163.
WARNING: Data from KSTU, MAS1 excluded day 164.
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)
for details:
