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, and ZIMM
- For the realization of the ITRF96 reference frame the following sites
are used (from GPS week 0947):
REYK, GRAZ, KOSG, MATE, ONSA, WTZR, ZIMM, ZWEN, VILL, POTS and BOR1
- 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.
