Course paper / final thesis, Internship

Space Thermal Analysis and TCS design for GEO VHTS Optical Communications Payload

Starting date

1 October 2021

Duration of contract

6 months


up to German TVöD 5

Type of employment


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

The successful applicant will support our team in the development of optical, photonic and communications systems for very-high-throughput satellite communications applications. Foremost, she/he will perform theoretical analysis and simulation of various techniques to characterize the space thermal environment and characterize the thermal control subsystem (TCS) related to the optical communication payload. Space environment analysis and TCS literature review would conclude the theoretical part, which shall be followed by simulation work on CAD and CAE software, to assess the most effective TCS solutions in terms of SWaP (Size, Weight and Power) and the most effective interfaces between the TCS and the Optical Communication Payload in the space environment.

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


  • thermal control subsystem design for optical communication payload
  • interface definition between the optical payload and the TCS
  • performance analysis
  • pogramming of Python or Matlab simulation tools

Your qualifications:

  • study direction of aerospace / communications / electronic engineering or physics
  • experience with CAD and CAE software
  • experience in thermal design and simulation is an advantage
  • interest in (satellite) optical communications

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 unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
