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 - 1056: BOR1, GRAZ, KOSG, MATE, ONSA, POTS, REYK, WTZR, ZWEN, VILL, GRAS NYA1, TRO1, THU1 - For the realization of the ITRF97 reference frame the following sites are used from GPS week 1057 onwards: BOR1, GRAZ, KOSG, MATE, ONSA, POTS, REYK, WTZR, 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.
