Job Description

Your mission:

The Optical Communications Group at DLR-Oberpfaffenhofen investigates new technologies to increase the data throughput between Satellites and Ground Stations, by employing free-space optical (FSO) links.

Such advanced technologies require sophisticated analysis of downlink signal quality to different locations and under varying atmospheric conditions.

In this thesis a setup for tracking, receiving, and measuring optical satellite signals shall be optimized and utilized to perform the according measurements with dedicated LEO satellites.

The thesis shall comprise the following:

  • research and testing of telescope hardware and control software
  • tracking tests with various laser targets
  • measurements of laser signals from satellites, employing cameras, power sensors, and data receivers
  • analysis of measured data, i.e. tracking-error, power scintillation, and received data

Person Specification

Your qualifications:

  • Study of Electrical Engineering, Physics, Mechanical Engineering, or similar
  • Programming  Matlab/Octave/Python, as well as flexibility and an autonomous mode of working
