Fraunhofer Creates Transceiver for Precise Data Flow Between Components in Satellite Systems

Fraunhofer Creates Transceiver for Precise Data Flow Between Components in Satellite Systems

Fraunhofer IPMS, a global leader in R&D services for electrical and photonic microsystems in the disciplines of smart Industrial solutions, medical and health applications, and improved quality of life, has created a transceiver that ensures data flow between the components and it has been on board the ISS (International Space Station) for testing reasons since February 2022.

There is international consensus in the space industry regarding the modularity of future satellite systems. In the future, such systems should be able to be flexibly disassembled and reassembled as in a modular system. The advantage of modular plug & play systems is that defective components can be replaced, thus significantly increasing the service life and function of a satellite. At the end of their lifetime, satellites either burn up in the earth's atmosphere or remain in earth's orbit. As a consequence, space debris is produced, which already generates enormous costs and effort and can become a real danger to life in manned space flight. The new generation of satellites will therefore replace the traditional architecture with a more sustainable and modular concept.

In order to be able to flexibly attach and detach modules directly in space, easy-to-couple and standardized components are particularly important. In addition to the mechanical coupling of the individual modules, it is essentially a matter of ensuring the transfer of data and energy between the individual modules so that satellites can be combined as required. For this reason, RWTH Aachen University applied for a patent years ago, which has now been brought to market by the spin-off iBOSS GmbH as iSSI (intelligent Space System Interface) and forms a standard interface for such systems.

Fraunhofer IPMS technology in space

Part of the interface is a development of Fraunhofer IPMS and also known as Li-Fi GigaDock. The core of the technology is an optical wireless transceiver, a highly integrated device that enables contactless full-duplex and bidirectional data transmission with a data rate of up to 5 Gbps. The possible transmission distance of the optical data interface is five centimeters. The component can also be used for rotor-to-stator transmission, as the transceiver functions perfectly even at high speeds.

"Building on this component, Fraunhofer IPMS has developed a communication module for iBOSS that has now made it into space, or to be more precise, even onto the ISS," says a delighted Alexander Noack, head of development for optical wireless communication. "In addition to space travel, the component can be found in industrial communication systems, in medical technology as well as in docking applications," he continues.

In February, the interface flew into space for testing and demonstration purposes and was mounted by a robot for the first time on the Japanese part of the ISS. The module is to remain there until mid-December and prove its operational capability under vacuum conditions and the influence of radiation.

Fraunhofer IPMS will exhibit its LiFi developments in hall B4 (booth B4.258) at the Electronica trade fair in Munich from November 15 - 18, 2022.
