🛰️ Advancing European RISC-V Computing for Space: Progress from the ISOLDE Project 🚀 The ISOLDE project continues to make strong progress toward bringing European RISC-V computing to the next generation of autonomous satellites. 🔬 Our latest update highlights the development of the ISOLDE Space Demonstrator — a key milestone showing how open hardware technologies can support onboard processing and decision-making in future space missions. 🌍 The demonstrator builds on lessons from ESA’s Sentinel-2 mission, targeting low-Earth-orbit use cases where real-time data processing and reliability are crucial. By combining high-performance RISC-V processors, domain-specific accelerators, and fault-tolerant architectures, ISOLDE is laying the groundwork for European-made, high-performance computing solutions ready to withstand the harsh conditions of space. 🔗 Read more about our latest developments: https://lnkd.in/d-9yhibn

📰 #NewPaper — Researchers from the i2CAT Research Centre Space Communications Group and Universitat Politecnica de Catalunya have developed a new evaluation tool for satellite quantum key distribution (QKD). This work, published by the IEEE Open Journal of the Communications Society, addresses the challenge of building secure, global communication networks by using satellites to overcome the distance limits of fiber optic cables. 🛰️🔐 The paper presents a new method to more accurately predict the performance of these satellite systems, validating the approach with real-world data from the Micius satellite experiments. This tool will help create more reliable and secure quantum communication systems. 🔗 Access the article: https://lnkd.in/diDN6q-w ➡️ Authors: Javier Jordán Parra, Marina Garcia Romero, Jano Gil Lopez, Joan A.

Commercialisation of high data rate services in the #6G era is currently constrained by the limited availability of #radiofrequency (RF) spectrum. This has led to growing interest in leveraging large blocks of spectrum in higher frequency bands to meet the increasing demand for peak #data rates and capacity in #wireless #communication links. Free-space optical (FSO) communication has emerged as a promising solution to address these limitations and enhance modern communication systems. A recently published technical paper in IEEE Transactions on Vehicular Technology, titled CubeSat-Enabled Free-Space Optics: Joint Data Communication and Fine Beam Tracking, authored by Hossein Safi, Iman Tavakkolnia, and Harald Haas from the University of Cambridge (#LRDC), Mohammad Taghi Dabiri from Hamad Bin Khalifa University and Julian Cheng from The University of British Columbia Columbia, specifically tackles the challenges of integrating CubeSats, a type of #nanosatellite used for #space research and #technology testing, with FSO links. The paper proposes joint #data detection and beam tracking, and explores how to overcome constraints related to size, weight and power in order to accelerate advancements in high-throughput, low-Earth orbit communication systems. You can read the full paper, which tackles the problem of data detection and fine beam tracking for ground-to-CubeSat FSO links using an array of avalanche photodiodes (APDs) at the receiver, via the following link: https://lnkd.in/eAqxyx3j The image below illustrates a graphical representation of a ground-to-CubeSat FSO link and parameters affecting the channel.

High efficiency in data transfer with XLink 📡 Recently, Julian Harbeck from the Chair of Space Technology - TU Berlin highlighted the strengths of our XLink SDR transceiver inside the TUBIN satellite. Launched over 4 years ago, the microsatellite depends on our XLink’s reliable performance to manage the high data rates needed for image transmission. We’re excited for future collaborations just like this one with the Technische Universität Berlin and the Deutsches Zentrum für Luft-und Raumfahrt e.V.!   🌌 See more successful projects that we have contributed to: https://lnkd.in/dabNj95e #IQspacecom #NewSpace #SatelliteCommunication

Day 4 at EDHPC 2025 brought another highlight from the DSI team in Elche! One of our R&D Engineers took the stage to present "MMU-NXT - A Next Generation High Data-Performance Mass Memory Unit", showcasing how we're addressing the growing demands for faster, more reliable data storage in space missions. As satellites and space instruments generate unprecedented volumes of data, solutions like MMU-NXT are critical for ensuring that mission-critical information is captured, stored, and transmitted efficiently. Our latest developments in mass memory technology represent a significant leap forward in performance and reliability. The response from the EDHPC 2025 community has been fantastic, with engaging discussions on how next-generation memory solutions will enable more ambitious space missions in the years ahead. When it comes to data handling in space, DSI continues to deliver innovation that matters. #EDHPC2025 #SpaceTechnology #MassMemory #Innovation #ForABetterSpace

TechTalk: Cooperative Offloading at the Edge: HAPS + LEO for AEU - International Journal of Electronics and Communications Infrastructure-Limited Regions Mobile edge computing (MEC) is transforming how we deliver computation-intensive services—but what happens when terrestrial infrastructure fails or doesn’t exist? A new paper on HAPS-assisted cooperative offloading for space–air–ground integrated networks (SAGIN) offers a compelling answer. By combining high-altitude platform stations (HAPS) with low Earth orbit (LEO) satellites, the authors propose a hybrid MEC framework that enables low-delay, high-throughput edge computing—even in disaster zones and rural areas. The architecture leverages: - HAPS for wide-area coverage and stable connectivity - LEO satellites for high-speed data transmission Ground users (GUs) offload tasks via HAPS to LEO satellites under a partial offloading mode, with a nonlinear optimization model jointly tuning task distribution and resource allocation. The result? Significant reductions in execution delay and maximized offloaded data—outperforming random and non-cooperative schemes. This is more than academic theory. It’s a blueprint for resilient ISR, tactical edge computing, and autonomous system support in denied environments. For those shaping the future of SAGIN, MEC, and aerial–orbital integration, this paper deserves a close read. #EdgeComputing #SAGIN #HAPS #LEOSatellites #SpaceIntel

The next generation of global connectivity won't be built on Earth. Non-terrestrial networks are moving from concept to reality, but the engineering challenges are formidable. Long-distance signal propagation, regulatory fragmentation across frequency bands, and the brutal economics of launching hardware into orbit (where every kilogramme still costs tens of thousands of dollars) are just the start. At Plextek, we're developing the solutions that tomorrow's NTN systems will need. Advanced techniques for managing non-linearity in massive arrays. AI-driven interference mitigation. Regenerative payloads designed for the realities of space. Over 35 years of RF expertise, and proven space heritage through our work on missions. The future of global communication is being engineered today. Learn more about our NTN capabilities here: https://bit.ly/4qMfsAw

While a large number of recent works have evaluated 5G and LEO satellite networks in the mainland US, their performance in non-contiguous US regions remains under-explored, despite their unique challenges and significant visitor demands. In our recent work, accepted in SIGMETRICS 2026, we present the first detailed evaluation of cellular and Starlink network coverage and performance in non-contiguous US regions through extensive drive tests covering over 4200+ km across Alaska, Maui, HI, and the mainland US (as a baseline). Our study shows a persistent digital divide between mainland and non-contiguous US for cellular networks in terms of coverage and performance, highlighting the challenges of cellular deployments in non-contiguous US regions. While Starlink provides substantially higher performance than cellular networks most of the time, area-specific challenges, including unique terrains in Hawaii and sparse satellite deployment in Alaska, significantly degrade performance compared to the mainland US. We also explore the spatiotemporal diversity between cellular and Starlink performance and study the potential of multipath transport to bridge the connectivity gap in non-contiguous US regions. This work is led by my 2nd year PhD student Sizhe Wang, and is joint work with my team members Moinak Ghoshal, Yufei Feng, Imran Khan, Phuc Dinh, Zhekun Yu, and our collaborators Omar Basit, and Y.
