For Section 1.2 "Global Geomonitoring and Gravity Field" outer branch in Oberpfaffenhofen (near Munich) we invite applications for a

PhD position (m/f)

Job Vacancy 0803

GFZ's Section 1.2 routinely estimates various Earth system parameters which describe the Earth's geometrical and physical shape (ground station coordinates or gravity field spherical harmonic coefficients) and its orientation in space (Earth orientation parameters (EOP)) based on observations of satellite orbit dynamics which can be observed by various types of satellite tracking data such as Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS), Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) and other data. Typical satellites we analyze are Low Earth Orbiters such as GRACE, TerraSAR-X or TanDEM-X, or higher altitude missions as the GNSS constellations, or geodetic SLR satellites such as LAGEOS or LARES. The satellite orbit dynamics are driven by conservative (the gravity field) and non-conservative (the drag by the atmosphere, pressure by solar radiation, etc.) forces which are modeled and parameterized in our core Earth Parameter and Orbit System software package EPOS. By evaluating the observations in the least squares sense, the parameters we are interested in can be inferred with high accuracy and at the same time highly accurate orbits can be determined. Keeping EPOS conform to the most recent international standards allows us to support the international IAG services ILRS (International Laser Ranging Service) and IDS (International Doris Service) by operating an Analysis Center and an Associate Analysis Center, respectively. The German project GGOS-SIM2 (the successor of GGOS-SIM) is aiming at simulating all the space-geodetic techniques for the generation of a global Terrestrial Reference Frame (TRF) in view of the requirements of the Global Geodetic Observing System (GGOS) being 1 mm accuracy and 0.1 mm/a long-term stability. GGOS-SIM2 is focussed on the combination of the space-geodetic techniques via so-called space ties, that is, one or more satellites having all space-geodetic techniques on-board.

You can expect a very diverse and challenging job in an international work environment that is characterized by exciting research projects. The compatibility of work and family life is of particular concern to the GFZ. Therefore, it offers the opportunity for flexible working time and workplaces. Moreover, there is a kindergarten located on the research campus.

The GFZ is a partner with Geo.X (, and as such it is well connected with other geoscience institutions in Potsdam and Berlin. Geo.X forms the largest regional cluster of geoscientific expertise in Europe and offers excellent opportunities for cooperation and development.

Equal opportunity is an inherent part of our personnel policy. Therefore we are particularly welcoming applications from qualified women. Severely disabled persons will be given preferential treatment in the case of equal qualification.

If you have any questions regarding this job offer, please feel free to call Ms Buge at +49 (0) 331-288-28878.
