JPL ANALYSIS REPORT GPS-WEEK 0915 (DAYS 201-207, DATES 1997 Jul 20 - Jul 26)
******************************************************************************
Submitted by the JPL IGS/FLINN Analysis Team:
J F Zumberge, D C Jefferson, M B Heflin, M M Watkins, F H Webb
all at the Jet Propulsion Laboratory, California Institute of Technology,
Pasadena, CA 91109.
Files listed below are available in Unix compressed format and can be
retrieved using anonymous ftp to sideshow.jpl.nasa.gov (128.149.70.41),

been sent to the CDDIS.

jpl09157.erp Earth rotation parameters for GPS week 915.
jpl09157.snx Ground station coordinates for GPS week 915, SINEX format.
jpl0915[0-6].sp3 GPS ephemerides for GPS week 915, sp3 format.
jpl0915[0-6].tro Ground station troposphere estimates for GPS week 915.
______________________________________________________________________________
Median Orbit Repeatability (see table below): 11.0 cm
Data from PRN18 were mismodeled on day 207 and have been excluded from this
day's analysis. Also, according to files obtained at USNO, a new satellite
PRN13/GPS43 was launched on day 204. No data were available or used in
this week's processing.
Beginning this week we add two new candidate stations, SELE and SOFI. As with
other sites, these stations 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)
SELE (Almaty, Kazakstan) 1046790.8361 4540257.1789 4342920.8758
SOFI (Sofia, Bulgaria) 4319372.3900 1868687.5700 4292063.8000
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 204.
WARNING: FAIR (not ALGO) used as reference clock days 205 and 206.
WARNING: MKEA (not ALGO) used as reference clock day 207.
WARNING: Data from FLIN, MKEA, SNI1, TAEJ, TAHI, ZWEN excluded day 201.
WARNING: Data from FLIN, GODE, KELY, LBCH, SNI1, TAEJ, TMGO excluded day 202.
WARNING: Data from FLIN, KELY, ZWEN excluded day 203.
WARNING: Data from ZWEN excluded day 204.
WARNING: Data from ANKR, ZWEN excluded day 205.
WARNING: Data from THU1 excluded day 206.
WARNING: Data from METS, POL2, QUIN excluded day 207.
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)
