______________________________________________________________________________
Beginning with week 692 following changes have been made in our analysis
scheme:
1. We used 6-minute data instead of 4-minute data
2. We increased the number of considered core sites by adding
Hobart, Kourou, Metsahovi, Onsala, Penticton, Westford
3. We changed our terrestrial reference frame to have more accurate initial
coordinates (solution of all 1993-data) and to have a better alignment to
the ITRF93-System. This results in a shift for the pole coordinates of
dx=0.0029 mas, dy=-0.0017 mas compared to our old reference frame.
The pole solution has a jump between days 100 and 101. In the file
gfz06927.erp we send also the corrected values from week 679 to 691.

SOLUTION CHARACTERISTICS
1. Software used : EPOS.P.V2
2. Definition of Terrestrial Reference Frame
Fiducial-free adjustment of all station coordinates.
These coordinates are then fixed in the determination of ERPs and ORBITS
3. Data used:
- undifferenced carrier phases
- 32 h arc solutions
5. Adjusted parameters:
- state vector of all satellites
- coordinate corrections
- daily ERPs
- tropospheric zenith path delay (6 h)
- y-bias, solar radiation scaling factor
- ambiguities
- STA and SV clock parameters of each observation epoch
