Satellite Systems & Space Science

Wir entwickeln Nanosatellitensysteme der nächsten Generation für wissenschaftliche, kommerzielle und NewSpace-Anwendungen und bieten dabei eine hohe Nutzlastkapazität sowie flexible Integrationsmöglichkeiten für komplexe Experimente im Orbit.

Aufbauend auf nachgewiesener Flugerfahrung durch mehrere erfolgreiche Satelliten- und Astronautenmissionen konzentrieren wir uns auf hochintegrierte Plattformen, fortschrittliche Kommunikationstechnologien sowie den Betrieb in sehr niedrigen Erdorbits (VLEO) und im Deep Space.

SOMP2: Development of a Nano Satellite to operate scientific payloads in space
Nanosatellite SOMP2 - Student OnOrbit Measurement Project - is clompletely developed, built and tested, has a volume of only 20x10x10 cm³, at a mass of 2 kg, and is carrying 3 main payloads:
- FIPEXnano - small sensor system to investigate residual gas particles in space
- TEG - thermo electric generator to demonstrate energy harvesting in space
- CiREX - material experiment to investigate the influence of space environment on nano materials

CNT-EMI / CiREX: Investigation and Tests of Carbon Nano Materials in Space and Research on orientation behaviors of CNTs in electromagnetic fields. 
The research focuses on the investigation of carbon nanotubes under harsh space condition (e.g. proton and electron radiation, visible light, atomic oxygen). We test these materials on ground and in space (CiREX on SOMP2 Nanosatellite). Applicaiton in space could be e.g. carbon nanotubes based electromagnetic interference (EMI) films. So we investigate the production and handling of carbon nanotube based composite and their alignment in electromagnetic fields in consideration of the environmental influence.
Current activities concetrate on the development of a multifunctional foil for protection against electromagnetic interference and simultaneous transmission of adjustable frequencies for communication tasks.

MOTAR: Development of a scalable and modular thermal analysis model for Pico and NanoSatellites, Investigation of new small componentes for thermal control
For Pico- and Nanosatellites we develop a user friendly tool that allows reseachers to analyse and control the thermal relations between various satellite components right from the beginning of the complex development process. We also develop and test new and small thermal control technologies applicable for these small satellites.

ELCH: Development of an electrochromatic space radiator with adoptable thermal emissivity and thermal absorbtivity 
The temperature of a spacecraft is mainly influenced by the balance between absorption of solar flux and the emission of its own heat to the cold cosmic background. We develop adaptable surfaces to influence and control both: emissivity and absorptivity of the satellites surface, so heating and cooling of the spacecraft can be controlled at a time without folding radiators. This will lead to significant benefits in the electrical power subsystem and a lower overall mass of the spacecraft.

FlexTEG: Development, Characterisation and Demonstration of Thermoelectric Systems for Power Harvesting in Space 
External and internal thermal loads on satellites induce high heat flows that are emitted to space. Thermoelectric generators (TEG) can convert these heat flows into electrical power - even during shadow phases. We analyse and test TEGs for autonomous supply of low-power-demands, although the efficiency of TEGs is expected to be low. Flexible TEGs can be attached to any curved surface, which makes them predestined for many space and terrestrial applications. With special consideration of the harsh space environment, we develop flexible thermoelectric layers which are printed on polymer substrates in thick film technology .
