The Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences is the national centre for geosphere research. As a member of the Helmholtz Association of German Research Centres we are part of the largest scientific organization in Germany. With approximately 1,400 employees our key mission is to secure a profound understanding of the systems and processes of solid Earth, to develop strategies and options for action in addressing global change and its impacts on a regional level, to understand natural hazards and to minimize associated risks, to ensure the sustainable provision of energy and raw materials for a high-tech society and to evaluate the influence of human activity on system Earth.
As a partner in Geo.X, the GFZ has access to an excellent network of other geoscience institutions in Potsdam and Berlin. This largest regional concentration of geoscientific competence in Europe offers first-class cooperation and development opportunities.
For section 1.1 Space Geodetic Techniques (department “Geodesy”), we are looking for a:

PhD student for GNSS development within the DFG Research Unit “Clock Metrology” (f_m_x)

Reference Number 7030

The PhD position is part of the DFG-funded Research Unit "Clock Metrology: A Novel Approach to TIME in Geodesy", which has the overall goal to realize innovative approaches using the observable "time" in geodesy. The advertised position in project "Time as observable in integrated ground and space-based GNSS analysis" is related to deterministic and stochastic modeling of high accuracy clocks in GNSS analysis. In addition to satellite clocks (especially GPS and Galileo), these will be H-masers at observation stations and optical clocks in Geodetic Observatory Wettzell and PTB Braunschweig. The interdisciplinary conception of the Research Unit in physics and geodesy, and novel hardware developments allow to work on highly innovative and exciting research topics. The project work is integrated into the GFZ activities within the International GNSS Service (IGS) in Section 1.1 “Space Geodetic Techniques”.

Your responsibilities:

  • Further development of GNSS processing with focus on deterministic and stochastic modeling of satellite and receiver clocks within the Research Unit
  • Global and local GNSS evaluations and investigations on the influence of the modeled satellite and receiver clocks on the different geodetic parameters
  • Specific investigations and evaluations for the partners in the other nine projects of the Research Unit (e.g., evaluation of new data sets, testing of new models)

Your qualifications:

  • Scientific university education in the field of geodesy, mathematics, computer science or physics
  • Experience in the analysis of GNSS datasets with scientific software packages
  • Experience in satellite orbit determination is an advantage
  • Good programming skills in FORTRAN and scripting languages (e.g. Perl, Python)
  • Very good command of the English language, both written and spoken
  • Willingness to collaborate in an interdisciplinary and international research environment
  • High motivation and personal responsibility

What we offer:

  • Ambitious and varied tasks in a dynamic and international research environment
  • State-of-the-art equipment
  • Public service benefits
  • Extensive training opportunities
  • Professional career advice offered by our in-house Career-Centre
  • Flexible working hours and conditions
  • Support with finding a good work-life balance offered by benefit@work
  • Institute day-care centre on site
  • Working at the Albert Einstein science park on the Telegrafenberg in Potsdam
  • Work place within walking distance of Potsdam main train station, or just a short ride on the shuttle bus

Start date: As soon as possible
Fixed-term: 4 years
Salary: The position is classed as salary group 13 according to “TVöD Bund (Tarifgebiet Ost)”. The salary group is determined on the basis of the Collective Wage Agreement and the respective personal qualifications.
Working hours: Part-time 75% (currently 29.25 h/week)
Place of work: Potsdam
