Einige numerische Anmerkungen zu der Messung und Auswertung von relativen Schwerenetzen

摘要

This article treats selected processing issues of gravity data, which were obtained with relative gravimeters in the frame of the densification of Berlin's gravity network. A selection of numerical computations regarding the transformation function that leads to the gravimeter readings as well as the estimation of the drift are presented. For the evaluation of the respective network we consider the standard adjustment schemes, that can be found in the literature of gravity network adjustment (such as free network adjustment, adjustment using certain constraints, elimination of some model parameters prior to the adjustment etc). The obtained numerical results are compared with an independent programming system for the adjustment of relative gravity networks in order to verify the validity of our computations and attempt a first assessment of applying the different adjustment strategies to the available field data.%Der Beitrag behandelt die Auswertung von Messungen mittels Relativgravimeter im Berliner Schwerenetz. Es werden Vergleiche mit verschiedenen Programmsystemen angestellt um eine Aussage über die Gültigkeit von verschiedenen Modellen machen zu können.
