Seevermessung mal anders
Zehn Tage Schweremessungen mit dem VWFS Deneb auf der Nordsee im Juni und Juli 2021

Wer Höhen mit globalen Navigationssatellitensystemen bestimmen will, benötigt eine Höhenbezugsfläche. In Deutschland ist die Höhenbezugsfläche das German Combined Quasigeoid (GCG). Diese wurde nun für die Nordsee neu bestimmt. Dazu wurden Schweremessungen durchgeführt. Wie die Messungen abliefen und was es dabei zu beachten gab, erklären die beteiligen Wissenschaftler.

Anyone who wants to determine heights with global navigation satellite systems needs a height reference surface. In Germany, the height reference surface is the German Combined Quasigeoid (GCG). This has now been newly determined for the North Sea. Gravity measurements were carried out for this purpose. The scientists involved explain how the measurements were carried out and what had to be taken into account.
