Einfluss von Modellen nichtkonservativer Kräfte auf GNSS Satellitenbahnen und auf Parameter globaler Lösungen

摘要

The impact of different non-conservative force modeling approaches on the GNSS (Global Navigation Satellite System) satellite orbits and on the derived global solutions is evaluated in this dissertation. In particular, a new model for the solar radiation pressure impacting GPS and GLONASS satellites has been developed, called adjustable box-wing model. This model reduces systematic errors found in the GNSS satellite orbits and in the derived geocenter Z-component, pole rates and station coordinates.
