"Cutting-edge research requires excellent minds – particularly more females – at all levels. Launch your mission with us and send in your application now!" Prof. Pascale Ehrenfreund - Chair of the DLR Executive Board

Your mission:

The Institute of Communications and Navigation develops and investigates new systems and methods for radio transmission and positioning. Disruptions of satellite missions and modern communication, navigation and remote sensing systems can be the consequence of perturbations in the ionosphere. Therefore, a team in Neustrelitz monitors investigates and models the ionosphere for many years.

The radio occultation (RO) technique provides one of the most effective space-based methods for exploring planetary atmospheres. The availability of numerous medium Earth orbit satellites deployed by Global Navigation Satellite Systems (GNSS) such as GPS, GLONASS, Galileo, BeiDou allows continuous monitoring of the Earth’s ionosphere and neutral atmosphere by tracking GNSS signals from low Earth orbiting (LEO) satellites.

In this context, we are looking for a student with strong interest on ionospheric research and ambition for team work. Your main task is the generation of improved ionospheric data sets using radio occultation measurements from different LEO satellites at different orbit heights and validation of 3D ionosphere models developed at DLR.

Your work will comprise the following tasks:

  • reprocessing of selected data sets from radio occultation measurements on board of LEO satellites CHAMP and GRACE
  • validation of the 3D Neustrelitz Electron Density Model (NEDM) which includes a family of ionosphere parameter models developed at DLR
  • study the climatology of the rate of TEC or the related index ROTI as a function of geophysical conditions (Solar activity, season, geographic/geomagnetic latitude, local time) and case studies of ROTI under geomagnetic perturbed conditions
  • collaboration with Shanghai Astronomical Observatory (SHAO) to monitor and understand ionospheric-plasmaspheric variations and processes by multi-satellite space-based GNSS observations

Within the frame of the student activity, you will work 10-20 hours per week.

Your qualifications:

  • University degree (Bachelor of Science) in physics, mathematics, meteorology, geodesy or a related subject and completed with a very good grade
  • analytical competence
  • programming skills in Python and C\C++

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy puts great value on a healthy work-life balance as well as equal opportunities for men and women. Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
