Owing to changes at the individual IGS Analysis Centers during these years the resulting time series of global geodetic parameters are very inhomogeneous and inconsistent. A geophysical interpretation of these long series and the realization of a high\u2010accuracy global reference frame are therefore difficult and questionable. In view of these deficiencies, the Technical Universities of Munich and Dresden decided to perform a reprocessing of a global GPS network over the last decade in a joint effort. First results of the reprocessing of 11 years of data show significant improvements in the quality and homogeneity of the estimated parameters and will allow for new geodynamic and geophysical interpretations. In the early years an improvement of the coordinate repeatability by a factor of more than 2 could be achieved. The formal errors of subdaily Earth rotation parameters could be reduced by 30%. Advanced modeling approaches like a mapping function based on numerical weather models, consideration of second\u2010 and third\u2010order ionospheric corrections and absolute antenna phase center corrections for receivers and satellites were tested to achieve further improvements.<\/jats:p>","DOI":"10.1029\/2005jb003747","type":"journal-article","created":{"date-parts":[[2006,5,3]],"date-time":"2006-05-03T06:37:10Z","timestamp":1146638230000},"source":"Crossref","is-referenced-by-count":122,"title":["Reprocessing of a global GPS network"],"prefix":"10.1029","volume":"111","author":[{"given":"P.","family":"Steigenberger","sequence":"first","affiliation":[{"name":"Forschungseinrichtung Satellitengeod\u00e4sie Technische Universit\u00e4t M\u00fcnchen Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Rothacher","sequence":"additional","affiliation":[{"name":"Forschungseinrichtung Satellitengeod\u00e4sie Technische Universit\u00e4t M\u00fcnchen Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Dietrich","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Planetare Geod\u00e4sie Technische Universit\u00e4t Dresden Dresden Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Fritsche","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Planetare Geod\u00e4sie Technische Universit\u00e4t Dresden Dresden Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"R\u00fclke","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Planetare Geod\u00e4sie Technische Universit\u00e4t Dresden Dresden Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Vey","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Planetare Geod\u00e4sie Technische Universit\u00e4t Dresden Dresden Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"13","published-online":{"date-parts":[[2006,5,2]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1029\/2001JB000561"},{"key":"e_1_2_6_3_1","doi-asserted-by":"crossref","first-page":"280","DOI":"10.1007\/BF03655319","article-title":"Higher\u2010order ionospheric effects on the global positioning system observables and means of modeling them","volume":"18","author":"Bassiri S.","year":"1993","journal-title":"Manuscr.
