61616: Student Electrical Engineering, Communications, Technical Physics or Optics (f/m/x) - Optical communications system design for GEO satellite communications

Updated: 2 months ago

The Group of Advanced Optical Technologies of DLR’s Institute of Communications and Navigation develops experimental laser communication systems for optical data links between satellites and optical ground stations as well as demonstrator platforms for testbed system verifications. The system development covers several disciplines such as optics, physics, electronics, programming and mechanics.

The successful applicant will support our team in the development of optical, photonic and communications systems for very-high-throughput GEO satellite communications applications. Foremost, she/he will perform theoretical analysis and simulation of various techniques to realise analogue and digital signal transmission together with link budget calculations. Electrical and optical signal distortion analysis would conclude the theoretical analytical part, which shall be followed by experimental work on the laboratory prototype, where the relevant system parametres can be verified. Successful laboratory tests would finally qualify the setup to be tested by the student with the team in an outdoor testbed.

It is an excellent opportunity to work on a cutting-edge topic, gain experience on a real optical hardware and improve your engineering skills.

Main Tasks:

  • optical communications systems design
  • interface definition between the sub-systems
  • performance analysis (link budget, SNR, BER)
  • setup of a laboratory demonstrator and its performance verification
  • programming of simulation tools (Python or Matlab) when necessary
