Report for GPS Week 653 (Days 194-200) from GFZ
===============================================
This report is generated by the GeoForschungsZentrum Potsdam (GFZ)
on a weekly basis for the International GPS Geodynamics Service (IGS).
PRODUCT SUMMARY
GFZ06537.EPH: GPS ephemerides for GPS Week 651 (SP3 format, pos. and vel.)
GFZ06537.ERP: Earth rotation parameter (UT1 corrections are not included)
GFZ06537.CLK: ST and SV clock parameters of each observation epoch (the
maser-based clock at Fairbanks is taken as reference clock)
GFZ06537.SUM: Summary file for reporting week
The above specified products are available at CDDIS. The ERP results are
submitted additional to IERS Central Bureau and IERS Sub Bureau for Rapid
Service and Predictions.

INFORMATIONS TO PRODUCT GENERATION
The calculation of the 7-day ephemerides file is described below.
Day of GPS Week 653 [Day 0=Sunday; Day 6=Saturday]
Arc No. 0 1 2 3 4 5 6
0 XXXX----
1 XXXX----
2 XXXX----
3 XXXX----
4 XXXX----
5 XXXX----
6 XXXX----
XXXX : The first day of the 2-day arc is used for ephemeris
dissemination
---- : The second day is used for quality control by overlap
The pole coordinates are estimated for three epochs (beginning
of each day) with the 2-day arc's. Using the above described
method (one day overlaps) there are three solutions for each
pole parameter. The submitted ERP-results are the mean values
of these different solutions.
- GFZ06537.EPH (Seven 1-day segments)

In the table below the overlap rms differences [m] in radial,
cross- and along-track component are presented.
