Area of research:

Diploma & Master Thesis

Job description:

Free Space Optical (FSO) communication systems not only overcome the bandwidth limitations of RF systems, but also offer improved power efficiency, security and size compared to their traditional counterparts. These characteristics are of very high interest for small satellites, which are an increasingly growing market. The Optical Communication Systems Group at the Institute of Communications and Navigation has been developing an optical communication payload for CubeSats, with the primary goal of demonstrating high speed optical downlinks between a CubeSat and Earth.

This master thesis is about a concept to extend the optical communication payload for CubeSats for inter-satellite-links (ISLs). This thesis shall evaluate the necessary technical extensions for extending the optical communication payload towards ISLs. Furthermore, it shall estimate performance figures, such as achievable data rates and develop the procedures for the link acquisition between two satellites via laser-link.
