Internship 6 months Oberpfaffenhofen, Germany
Uploaded 29 Apr 2020
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
- Study of Electrical Engineering, Physics, Mechanical Engineering, or similar
- Programming Matlab/Octave/Python, as well as flexibility and an autonomous mode of working
