Deterministic wireless protocol for satellite control
Prof. Dr. Sergio Montenegro (Universität Würzburg)
Innocube is the first wireless Satellite ever. We are building a satellite without harness. Harness is heavy, complex, expensive, and very fault prone. Wireless protocols can overcome all these drawbacks, but we have to implement real time determinism and robustness and at the same time they shall have very low power consumption. In this presentation I will show the Innocube Project, its mission, components and development method, Specially the wireless avionic and the new developed real time and deterministic radio protocol.
Prof. Sergio Montenegro was born in Guatemala.
Since 2010, he has been Professor of Aerospace Information Technology
at the University of Würzburg. He develops control systems for satellites,
drones, aircraft, underwater vehicles, etc.
Focus: Reliable systems, survival machines.
Previously: Fraunhofer Gesellschaft + DLR – Space Systems
The XtratuM Hypervisor as Key Enabling Technology for New Space: A Success Story
Paco Gómez Molinero (FENTISS S.L.)

As of today, the XtratuM hypervisor, developed by the Valencia Polytechnic University spin-off FentiSS, has been added to 250 satellites that are already orbiting Earth. XtratuM allows all the application of a satellite, such as position and orbit control, mission control, the telemetry and telecommand subsystem that communicates with the control centre on the Earth, etc., to execute on the same computer, without need for separate computers and while guaranteeing non-interference. However, its true potential lies in supporting a new endeavor that came to be when we realized that missions typically performed by satellites as large as a bus, can now even better be performed with a group of small satellites, weighting only 100 – 200 kg, that interact in constellations. In this talk, I will introduce Xtratum and the success story we had with Xtratum in this New Space endeavor.
The profesional career of Paco Gomez-Molinero in the last 20+ years was determined by the eight years he spent at the European Space and Technology Center (ESTEC) in The Netherlands as staff member. Since then, he has acquired a 360 degrees perspective in developing all aspects related to technology and business innovation, covering strategic innovation plans, national and European funding and implementation details in all phases of an innovation project up to the marketing and successful commercialization phase. Activities developed in more than forty international R&D&I projects have kept him in contact with Excellence Center of outstanding companies such as Thales, Philips, Nokia or Sagem as well as first level R&D institutions such as Inria, CNRS, Fraunhofer Institute, VTT (Finland), TU Vienna, University of Reading, University of York, and University of Trento to name a few. Since 2018, he is CEO of fentISS, a technology-oriented SME who provides unique time-space partitioned systems for aerospace and other advanced real-time markets.
Hardware reconfigurable platforms for mixed criticality applications in space

Current and future space missions demand sophisticated on-board data processing functionalities, while low resources consumption remains a constraint. Using in-flight dynamically reconfigurable FPGAs allows enhancement of on-board processing with unprecedented levels of flexibility, enabling the adaptation of the system regarding functional and fault-tolerance requirements, subjects to change during mission lifetime.
After already having demonstrated the usage of in-flight reconfigurability for SRAM-based FPGAs for the PHI instrument on Solar Orbiter (SO/PHI), we aim for using the available powerful FPGA platforms, which are becoming meanwhile available also for space applications, for HW acceleration of critical control tasks integrated with high performance computing tasks in onboard computers. We present the current approaches of IDA for HW-reconfigurable computing under real-time constraints and the roadmap for future space applications.
Prof. Harald Michalik received the degree in electrical engineering and the doctoral degree from TU Braunschweig, Germany, in 1982 and 1991, respectively. After some years in the space industry, he received a professorship for information electronics in Bremen. Since 2001, he holds a professorship on Spaceborne Computers Design with the Institute of Computer and Network Engineering (IDA), TU Braunschweig.
