The cable harnesses in satellites contributes to an increased overhead, both in development and testing, as well as in weight and complexity. Cables and connectors are susceptible to wear.

Data transmission via radio frequency already offers the possibility of reducing these cable harnesses. However, this introduces the problem of electro-magnetic interferences.

In the SatelLight project different components, modulation schemes and encodings for intra-satellite LiFi communication are researched.

LiFi increases bandwidth, real-time capability, robustness and reliability of the intra-satellite communication. In addition, eavesdropping security is increased because light is limited within the walls. Furthermore, the use of light for autonomous operation of components is investigated.

A LiFi transceiver is developed using the knowledge gained from the project and spatial structures are optimized.
