Best Publication Award 2023

December 13, 2023. Our institute awarded the “Best Publication 2023 Award” to Kevin T. Li. The winning publication entitled “A Techno-Economic Assessment and Tradespace Exploration of Low Earth Orbit Mega-Constellations” has been authored by Christian A. Hofmann, Harald Reder, Andreas Knopp and Kevin T. Li.
This work presents a novel techno-economic framework, offering insights and quantifying the impact of changing parameters within the complex architecture of satellite constellations. The authors propose an enhancement to the existing framework using a common system engineering technique known as tradespace exploration. This approach provides clearer insights into the conceptual design of systems and a better understanding of the 'physics' behind proposed solutions. It enables a deeper analysis of key system parameters and performance indicators in such systems. Initially, the authors introduce key players in the ecosystem of mega-constellations, highlight recent advances leading to the rebirth of the concept of broadband LEO constellations, and develop initial rationale for key parameters in the cost model. Subsequently, they detail the applied techno-economic cost framework, extended through tradespace exploration. The authors present the optimal solutions derived from the exploration within the system, as indicated by the Pareto front of all results, and provide detailed insights into the interrelationships among specific key parameters. Overall, this work provides a comprehensive view of the intertwining possibilities within mega-constellations and lays the groundwork for further exploration of system design concepts for satellite constellations.

ASMS Best Paper Award

M.Sc. Eriserdi Mollaymeri, research assistant at the institute for information technology of Prof. Dr.-Ing. Andreas Knopp was awarded the prestigious “Best Paper Award” on 9th September 2022 at the 11th “Advanced Satellite Multimedia Conference (ASMS)” held in Graz, Austria.
The paper of Mr. Mollaymeri, coauthored with his research group leader Dr.-Ing Thomas Delamotte, is entitled: “Timing Alignment of Distributed Gateways: Theoretical Analysis and Experimental Demonstration”. This work addresses one of the challenges encountered today in the design of very high throughput satellite (VHTS) systems: the synchronization of the gateway stations used to uplink signals to the satellite. Thanks to this study, which has also been based on an experimental verification, a better understanding of the basic design trade-offs in the gateway to satellite links has been acquired. The findings of this paper pave the way to more efficient ground segment infrastructures.
The “Advanced Satellite Multimedia Conference” is one of the most renowned conferences on satellite communications, this year organized by the DLR Institute for Communications and Navigation and supported by the European Space Agency (ESA). The conference was held in conjunction with the 17th “Signal Processing for Space Communications Workshop”.

AFCEA Master Thesis Award

May 12, 2022: The master thesis of First Lieutenant Jonas Hofmann was awarded a 3rd Prize at the AFCEA Symposium in Bonn. The thesis “Cyclostationary Signal Detection and Doppler Rate Correction for LEO Nanosatellites in the ISM Band” tackles the problem of detecting the presence of communication signals after transmission over a low-earth-orbit (LEO) satellite channel. Especially the severe Doppler effects in LEOs, the low transmit power of small satellites and an environment of strong interference render this a challenging problem. The results can be used for a variety of applications such as civil cognitive radio tasks and or military signal intelligence. The thesis was supervised by Prof. Andreas Knopp and written as a research collaboration at the Naval Postgraduate School’s Space Systems Academic Group (SSAG) in Monterey, CA. The SSAG has been a pioneer in building and operating small satellites for many decades. Ongoing follow-up work of Hofmann’s thesis was partially published at IEEE conferences and will be part of the project SeRANIS.

Best student paper award

April 08, 2022: The paper „Capacity Analysis of a MIMO Laser Link from Lunar Surface to Earth” won the Student Best-Paper-Award in the IEEE International Conference on Space Optical Systems and Application (ICSOS 2022). The paper was written by the authors group from University of Bundeswehr Munich (UniBw M) and the German Aerospace Center (DLR): Hung Le Son, Robert Schwarz, Marcus Knopp, Dirk Giggenbach and Andreas Knopp. In this paper, a precise calculation was built to investigate the fluctuation of channel capacity of a multiple-input multiple-output (MIMO) laser link from lunar surface to Earth. Using the results of this calculation, the authors proposed the methods to mitigate the fluctuation and maximize the channel capacity. The paper also showed the potential of the MIMO technology in the laser communications. It increases not only the capacity and, thus, the data transfer rate, but also the reliability of the communication channel. The UniBw M cooperates with the DLR and especially its research center in the field of space travel and space communication. The cooperation has been intensified since 2021 in the project SeRANIS.

Best Publication Award 2021

December 21, 2021: The Institute for Information Technology awarded the “Best Publication 2021 Award” to the authors of the paper entitled “Emergency 5G Communication on-the-Move: Concept and field trial of a mobile satellite backhaul for public protection and disaster relief”. The paper was written by Florian Völk, Robert Schwarz, Mario Lorenz, and Andreas Knopp and has been published in the International Journal of Satellite Communications and Networking. The paper is part of the Special Issue 2021: “Satellite Networks Integration with 5G”.

The authors propose and investigate architectures for mobile Public Protection and Disaster Relief (PPDR) networks with satellite backhaul to ensure Communication on-the-Move. The results show that already existing interfaces of the 3GPP standard allow satellite-based 5G networks tailored to the needs of government authorities.

Best Publication Award 2020

Dezember 23, 2020. The Institute for Information Technology awarded the “Best Publication 2020 Award” to Kai-Uwe Storek. The winning publication entitled “Multi-Satellite Multi-User MIMO Precoding: Testbed and Field Trial” has been authored by Robert Schwarz and Kai-Uwe Storek. The paper, which was presented at the flagship conference IEEE International Conference on Communications 2020, demonstrates a complete satellite transmission scenario applying full frequency reuse – an upcoming technique for V/UHTS satellites to further improve the spectral efficiency of satellite systems. The impressive demonstration involved two co-located geostationary satellites that jointly utilize a common frequency band as well as two COTS DVB-S2x receivers. With on-ground MU-MIMO precoding for spatial multiplexing and advanced synchronization algorithms, the authors prepared and implemented an end-to-end testbed for the next generation of UHTS and fractionated satellite systems.
Congratulations to Kai and Robert!

Award for PhD student Matthias G. Schraml

December 23, 2017 The Institute for Information Technology awarded the “Best Publication 2017 Award” to Matthias Schraml who authored the publication entitled “Blind Estimation of the HPA Operating Point in Multicarrier Satellite Transponders”. The paper, which appeared in the renowned journal ‘’IEEE Communications Letters’’, proposes a novel method for the estimation of the operating point in satellite transponders when the input signal is of multi-carrier type and unknown to the measurement device. Operating point estimation has always been a problem if high practical relevance because satellite operators want to drive their transponders close to saturation for maximum power efficiency while preserving a distinct back-off to limit the intermodulation noise. The novel method opens up a strategy to measure the operating point without any a-priori knowledge about the signal and from any position within the satellite beam. Congratulations to Matthias!
