German Aerospace Center (DLR)

Start your mission with DLR

The German Aerospace Center (DLR) is the national aeronautics and space research centre and the space agency of the Federal Republic of Germany. Here, 8000 employees work together on a unique variety of topics in the fields of aeronautics, space, energy, transport, digitalisation and security. Their missions range from basic research to the development of innovative applications and products for tomorrow. Cutting-edge research requires excellent minds – particularly more females – at all levels, who fully achieve their potential in an inspiring environment. Launch your mission with us.
For our institute of Communications and Navigation unit Lorem Ipsum in Neustrelitz, we wish to recruit a qualified

Physicist, Mathematician, Meteorologist

Ionospheric Radio Occulation
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 scientist with strong interest on ionospheric research and ambition for team work. Your mission is the new algorithms development and improvement of the radio occultation retrieval technique by including topside ionosphere and plasmasphere content above the LEO satellite orbit height.
Your work will comprise the following tasks:
  • Development and testing of inversion techniques by using data sets from different LEO satellites at different orbit heights
  • Development of correction algorithms for mitigating higher order effects in space based total electron content (TEC) estimates
  • Estimates of improved LEO DCBs by combining ground and space based GNSS data
  • Investigation of ionospheric-plasmaspheric variations processes and mechanisms such as [O] / [N2] ratio, vertical plasma drift and electric fields variations during storms, Nighttime Winter Anomaly (NWA), E-layer dominated ionosphere (ELDI) and asymmetry etc,
  • Collaboration with Shanghai Astronomical Observatory (SHAO) to monitor and understand ionospheric-plasmaspheric variations and processes by multi-satellite space-based GNSS observations
  • Presentation of research results in international journals and at scientific conferences
Your qualifications:
  • completed academic university degree (Diplom/Master) in physics, mathematics, meteorology, geodesy or a related subject with very good results
  • completed Doctor of Philosophy (PhD) or comparable scientific degree in physics, mathematics, meteorology, geodesy or a related subject with very good results
  • analytical competence, traceable expertise in data analysis and knowledge in statistics
  • experience in the analysis of GNSS based ionosphere data
  • fundamental programming skills in Python and C\C++
  • knowledge/experience in the field of computer-aided data acquisition and evaluation
  • knowledge of Linux/Unix and Windows operating systems
  • ability to work in a team as well as independent and goal-oriented
Your benefits:
DLR is an employer that values your commitment and promotes your professional and personal growth through a range of qualification and training opportunities. Our unique working environment offers our employees a great deal of freedom and an incomparable infrastructure, in which you will be able to fulfil your mission.
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.
