Abstract:: By applying regional gravity field determination, globally consistent satellite or gravity models can be combined with local gravity field measurements to calculate potential values and physical heights at reference stations of the International Height Reference Frame (IHRF) with high accuracy. This dissertation derives 'Residual Least-Squares Collocation' as a new method for regional gravity field determination, and evaluates its advantages for the calculation of gravity-derived quantities at IHRF reference stations. «

Translated abstract:: Durch die Verwendung regionaler Schwerefeldmodellierung können global konsistente Schwerefeldmodelle mit lokalen Gravimetriemessungen kombiniert werden, um Potentialwerte und physikalische Höhen an Referenzstationen des Internationalen Höhenreferenzrahmens zu bestimmen. Diese Dissertation präsentiert die "Residual Least-Squares Collocation" als neue Methode der regionalen Schwerefeldmodellierung und evaluiert deren Vorteile für die Berechnung der entsprechenden Schwerefeldfunktionale.
