Processing Strategy:
--------------------
- The combined weekly EUREF solution (EUR) is 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.
The rescaling factors of all centers are chosen such that they give
the resulting EUREF solution realistic formal errors.
- To align the EUREF weekly solutions with the terrestrial reference frame
a selected set of "reference stations" is fixed to their ITRF coordinates.
- For the realization of the ITRF94 reference frame the following sites
were used (from GPS week 0860 to GPS week 0946):
BRUS, GRAZ, KOSG, MATE, METS, ONSA, WTZR, ZIMM
- For the realization of the ITRF96 reference frame the following sites
are used from GPS week 0947 - 0981:
BOR1, GRAZ, KOSG, MATE, ONSA, POTS, REYK, WTZR, ZIMM, ZWEN, VILL
From GPS week 0982 - 1020:
BOR1, GRAZ, KOSG, MATE, ONSA, POTS, REYK, WTZR, ZIMM, ZWEN, VILL, GRAS
- For the realization of the ITRF97 reference frame the following sites
are used from GPS week 1021 onwards:
BOR1, GRAZ, KOSG, MATE, ONSA, POTS, REYK, WTZR, ZWEN, VILL, GRAS
NYA1, TRO1, THU1
- 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: - Sites GRAS 10002M006 and TRO1 10302M006 have been excluded from the
combination because of few Rdays with data
Sites MAS1 31303M002, SFER 13402M004 of one AC have been excluded
from the combination due to large residuals
