Terrestrial Gravimetry

  • A mobile absolute gravimeter based on atom interferometry for highly accurate point observations
    Atom interferometers have demonstrated a high sensitivity to inertial forces. The Gravimetric Atom Interferometer (GAIN), developed at Humboldt-Universität zu Berlin, is a mobile atom interferometer based on interfering ensembles of laser-cooled Rb-87 atoms in an atomic fountain configuration. In the continued development state-of-the-art superconductiong gravimeters and laser-interferometer based absolute gravimeters are used for comparisons with and the characterization of GAIN.

Relativistic Geodesy

  • High-performance clock networks and their application in geodesy
    The rapid development of optical clocks and frequency transfer techniques provides the opportunity to compare clocks’ frequencies at the uncertainty level of 10-18. This will enable relativistic geodesy with the aimed accuracy of cm in terms of height. Clock networks are thus highly relevant to various geodetic applications, such as the realization of a height reference system and the determination of regional/global gravity fields. In this project, we aim to investigate the potential of high-performance clock networks and quantify their contributions to specific applications through dedicated simulations.

Space Sensor Technologies

  • Modellierung mit Quantensensoren gestützter Satellitenmissionen
    Dieses Projekt beschreibt den den Einsatz von Beschleunigungsmessern auf Grundlage von Atominterferometern in Schwerefeldsatellitenmissionen. Es wird sowohl der Ersatz klassischer elektrostatischer Beschleunigungsmesser durch Quantensensoren als auch die Kombination beider Sensorarten in einem Hybridsystem untersucht.
