JPL ANALYSIS REPORT GPS-WEEK 0900 (DAYS 96-102, DATES 1997 Apr 06 - Apr 12)

Submitted by the JPL IGS/FLINN Analysis Team:

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),
directory pub/jpligsac/0900. These files (except for *.tro) have also
been sent to the CDDIS.

Median Orbit Repeatability (see table below): 20.0 cm
According to IGS Mail No. 1566, the receiver at PAMA (Pamatai, Tahiti) was
moved to a new location and renamed TAHI. Although data from the new station
were used in last week's (899) analyses, statistics reported for the site after
day 090 in our Analysis Center weekly report and SINEX file (jpl08897.sum,
jpl08997.snx) were incorrectly labeled "PAMA". The SINEX file has been
corrected, and resubmitted to the CDDIS and the IGSCB. As usual, TAHI is given
the opportunity to participate in the orbit and clock solution as the global
site distribution varies. The following nominal coordinates were assumed for
weeks 899 and 900 only:
X (m) Y (m) Z (m)
TAHI (Papeete, Tahiti): -5245195.2928 -3080472.2325 -1912825.4175
According to the file nanu1997.mes obtained from the IGS CBIS, PRN06 was
unusable on day 097 for maintenance/repositioning. Data from this satellite
did not meet our initial convergence criteria on this nor the previous day
(096), and have been excluded from the analyses of both days.
Data from PRN28 has not been available since week 878 (see nanu1996.mes).
Beginning this week, data from this satellite is included in our analyses
again. However, data volume was sufficiently low, and mismodeling was such
that its solution is not included in our sp3 products for the week, nor is it
present in our engineering data summary table.
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 days 096-098.
WARNING: FAIR (not ALGO) used as reference clock days 099-100.
WARNING: Data from PRN06 excluded days 096 an 097 due to a maneuver.
WARNING: Data from BAHR, BOGT, CAS1, HART, HRAO, IISC, KERG, KIT3, MALI, MCM4, TAHI, YAR1 excluded day 096.
WARNING: Data from ONSA excluded day 098.
WARNING: Data from HOPB, HRAO, MDVO, ONSA, TIDB excluded day 099.
WARNING: Data from HOPB, USNA, WTZR excluded day 100.
WARNING: Data from BOR1, HOPB, KELY, SNI1, USNA, WTZR excluded day 101.
WARNING: Data from CAS1, SANT, USNA, WTZR excluded day 102.
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)
