REMARK:
This week GFZ has started to use the set of ITRF96 station coordinates.
The sites given in the official ITRF96_IGS_RS47 (Altamimi) were constrained
to the given coordinates and velocities.
This week was analyzed using the old ITRF94 coordinates and core sites, too.
We found the following differences in the polar motion parameters
from ITRF94 to ITRF96:
PMx: -0.09 +- 0.03 PMy: -0.01+- 0.02

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
- 24 h arc solutions
5. Adjusted parameters:
- state vector of all satellites
- coordinate corrections
- daily ERPs
- tropospheric zenith path delay (4 h)
- y-bias, solar radiation scaling factor
- ambiguities
- STA and SV clock parameters of each observation epoch
