PRODUCTS UPDATE
We are pleased to announce the availability of JPL's weekly station coordinate
solutions in SINEX format. Solutions have been submitted since GPS week 813.
Please note that these are loosely constrained free-network solutions. The new
files can be obtained in the same manner as our sp3 orbit products as mentioned
above. Comparisons of SINEX files submitted by Analysis Centers can be found
in a separate report.
GENERAL
According to the file nanu1995.mes obtained from the IGS CBIS, PRN28 was
unusable on day 270 for maintenance/repositioning. Data from this satellite
did not meet our initial convergence criteria on this and the following day,
and have been excluded from our analyses accordingly.
Beginning this week, we include data from several new stations. As with most
stations, these sites 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)
ANKR (Ankara, Turkey): 4121949.7200 2652189.4686 4069024.5985
COSO (China Lake, CA USA): -2411191.9800 -4571453.5100 3727489.5700
GOPE (Ondrejov, Czech Republic): 3979326.3751 1050321.5602 4857060.4141
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 AOA1, DAV1, HART, KERG, SEY1, VCIO, WSMN excluded day 267. NLIB used as reference clock on this day only.
WARNING: Data from AOA1, DAV1, HART, LAMA, NYAL, PAMA, SEY1, WETT, WINT
excluded day 268. YELL used as reference clock on this day only.
WARNING: Data from PRN28 excluded days 270 and 271 due to a manuever.
WARNING: Data from COSO, DAV1, HBRK, MCM4, METS, TROM, VNDP, WETT excluded day
273.
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)
