Processing Strategy:
--------------------
- The combined weekly EUREF solution (EUR) was created after removing the
Analysis Center specific constraints.
- Covariance rescaling factors are derived from the sampling rate used by
each center.
In fact all solutions contribute to the combined solution with the same
weight.
- We perform free network solutions, specifying 6 no-net translation and
rotation constraints to define the geodetic datum of the combined solution.
We use the ITRF93 coordinates (up to GPS week 0859) respectively
the ITRF94 coordinates (since GPS week 0860) of the sites BRUS, KOSG, MADR,
MATE, WETT, GRAZ and ZIMM to align the free solutions with the terrestrial
reference frame.
- The comparisons between each individual solution and the combined solution
is done using a 7-parameter Helmert transformation. The Helmert parameters
are determined using all sites of the individual solutions.
- In the first Table unweighted rms values (for the coordinate components in
the local system North-East-Up), derived from the Helmert residuals, are
shown for each site.
- In the second table an (unweighted) rms is computed for each Analysis Center.
These values are derived from the Helmert residuals of all sites of a
particular Analysis Center.

REMARKS: - HERS was excluded for the Analysis Centers IFG and ROB.
At CODE problems were detected for 4 days in this week
(see COE08667.SUM) causing systematic effects mainly
in station height (e.g. comparing with the HERS time series
of the last 2 months). That is the reason for excluding
the results of IFG and ROB instead of COE.
