3 Keynote: Miguel Cordero (ESA): Celeste: paving the way towards Positioning, Navigation and Timing in Low Earth Orbit (LEO-PNT)

Biography
Miguel Cordero joined the European Space Agency as Radionavigation Engineer in 2015. He has been providing support to the navigation programmes (EGNOS and Galileo) as well as to other missions making use of space GNSS receivers. Since 2020 he has been supporting the activities related to LEO-PNT carried out by the Agency including Celeste IOD mission. Before joining ESA he worked in the development of navigation modules for UAV autopilots.

Abstract
Positioning, Navigation, and Timing (PNT) services enabled by Global Navigation Satellite Systems are foundational to the functioning of modern society. Despite the significant impact of PNT in economy and society, GNSS systems face well-documented limitations. Low Earth Orbit (LEO) satellites have emerged as a promising solution to address these challenges. ESA’s LEO-PNT initiative, the Celeste In-Orbit Demonstrator (IOD) aims at validating enabling technologies such as frequency-diverse signal generation and transmission, on-board orbit determination and time synchronization, and advanced small satellite platforms, to demonstrate the feasibility and benefits of augmenting existing GNSS with a LEO-based layer. Beyond the Celeste IOD, ESA is working with the European Union towards defining a potential EU LEO-PNT operational system in complement to EGNOS and Galileo. The next phase, the Celeste In-Orbit Preparatory (IOP) phase under ESA’s FutureNAV programme, will encompass technology development, industrialisation and in-orbit validation. This phase will be instrumental in shaping future operational LEO-PNT initiatives institutional or commercial.

13 Radiation Hardness Assurance for Complex Devices: The Untold Story

Abstract
For space systems, particle ionization can cause faults in microelectronics that inhibit operation and hence reduce reliability. In turn, radiation hardness assurance methods have been developed to perform system failure analyses. These practices have been applied for decades and are now in need of being modernized for better characterization of today’s complex system applications. This presentation describes what is required to test and analyze complex components such as SoC and FPGA devices, how conventional methods are insufficient, and how new methods can provide optimal coverage for failure analyses.

26 Satellite-as-a-Service Architecture for ML Edge Computing on Heterogeneous Processing Platforms

This paper presents a Satellite-as-a-Service (SaaS) architecture designed to enable flexible and efficient deployment of Machine Learning (ML) workloads on heterogeneous edge hardware platforms in space. Leveraging container-based virtualization (Docker) and an orchestration framework (Kubernetes), our approach abstracts hardware complexity and supports a variety of accelerators — FPGAs, TPUs, VPUs and NPUs — within a unified development and deployment environment. We integrate DevOps design principles delivering a reconfigurable stack that supports rapid ML model updates and deployment on target hardware. By treating satellites as extensible service platforms, we demonstrate how containerization and hardware abstraction streamline the onboarding of advanced ML algorithms, ranging from convolutional neural networks for image processing to neuromorphic paradigms for ultra-low-power inference. We detail how standardized APIs and modular workflows promote interoperability across multiple satellite systems and heterogeneous hardware accelerators.

30 A Generic SpaceWire Transport Layer

The transport layer is the essential part in the open system interconnection (OSI) reference model, since it is the interface between the software-oriented layers 5-7 and hardware-oriented layers 1-3. On the one hand, it provides a general approach for data exchange with the software-oriented layers, independent of the underlying hardware. On the other hand, it is responsible for an efficient and reliable use of the underlying hardware. These characteristics make the transport layer crucial for the effective usage of a communication system, as it significantly reduces the implementation effort for the software-oriented layers.

The lack of a transport layer is a huge disadvantage. Combining the functionality of different communication layers into single application specific protocols can lead to the coexistence of multiple, non compatible approaches, resulting in a higher implementation effort for integrating new applications. Therefore, the existence of a transport layer is fundamental for both communication software and hardware, to provide established communication concepts, which are a precondition for the use of standardized software libraries, and to integrate modern computing trends (e.g. Big Data, Data-Mining, machine learning, cyber security).

SpaceWire does not yet define a general transport layer. This paper presents the approach of a minimalist SpaceWire transport layer, as common base for the implementation of higher level protocols. It comprises both the hardware related SpaceWire transport node and the associated software counterpart as well as the associated protocol. The transport layer implementation is one result of our longstanding SpaceWire development and is already in use in several robotic systems.

39 A Camera Payload and Processing Unit for Autonomous Satellite Deployment Verification accelerated by Soft GPU

Engineering Minds Munich GmbH has developed a Camera Payload and Processing Unit (CPPU) for in-orbit monitoring and verification of satellite deployables. Reliable confirmation of solar panel or antenna deployment remains challenging for small satellites due to limited telemetry bandwidth and constrained power budgets.

The CPPU provides a compact and dependable solution by integrating camera interfacing, image buffering, and actuator control into a single unit. Cameras can be placed up to 1 m from the processing board, enabling flexible positioning for optimal visibility of critical mechanisms. Built on FPGA and bare-metal software, the platform emphasizes deterministic operation, testability, and robustness in the space environment. A flight model has already been delivered and validated, demonstrating the maturity of the development.

Current developments extend the CPPU with autonomous deployable-shape extraction, using a soft-GPU accelerated pipeline. The approach reduces image data from 8 Mbit to 1.6 kbit (a three orders-of-magnitude reduction) while retaining key geometric information in vectorized format.

74 High-Performance, Multi-Lane, SpaceFibre Routing Switch for ADHA

The Advanced Data Handling Architecture (ADHA) concept has been developed in collaboration between European industry (integrators, and hardware suppliers) and the European Space Agency (ESA). ADHA defines a set of specifications for electronic data-handing units [1]. which is based on standardised, interchangeable, and interoperable electronics modules. SpaceFibre [2] provides the high data-rate interconnect for ADHA, both inside an ADHA unit, interconnecting the AHDA modules, and externally. This paper describes a SpaceFibre routing switch for AHDA hardware modules which is able to support the demanding data rates and interconnect architecture of ADHA applications.

76 Real-Time Onboard Data Accumulation and Pre-Processing for the Photospheric Magnetic field Imager on ESA’s Vigil mission

ESA’s Vigil mission is an operational mission planned to monitor the solar drivers of space weather conditions from the Lagrange point L5. The Photospheric Magnetic field Imager (PMI) on this mission shall provide full-disk vector magnetograms of the solar photosphere at a cadence of 30 minutes with 20-minute latency for its priority-1 data products. In addition, raw filtergrams and high-cadence line-of-sight magnetograms and Dopplergrams at a cadence up to 1 minute will be provided as supplementary data products. To meet the real-time processing requirements imposed by the telemetry volume, onboard pipelines are implemented in the processing unit hardware to produce low latency data products. In order to handle this computationally heavy task while meeting the latency requirement of the mission, the pipelines are implemented on a Field Programmable Gate Array (FPGA). This paper describes the series of steps involved in the first part of onboard data processing – from image acquisition and accumulation to polarimetric demodulation. It also discusses the parallel processing of the three pipelines in a resource-constrained FPGA in order to obtain a real-time processing environment which complies with PMI’s stringent requirements on accuracy, stability and reliability with the limited resources available on a deep space mission.

92 Hera AI FDIR - On Board Telemetry anomaly detection using ML

Abstract— Autonomous fault and anomaly detection is critical for ensuring the safety and success of space missions, addressing the limitations of ground-based analysis due to bandwidth constraints and operational delays. The conventional approach in Space Operations involves using Out-of-Limits (OOL) alarms for anomaly detection, which may prove insufficient in identifying and responding to complex anomalies or unforeseen novelties within the range of nominal values [1], [2]. In our previous work [3], we proposed a Machine Learning (ML) approach for on-board telemetry anomaly detection that addresses these limitations. We demonstrated a proof-of-concept integration of a TensorFlow model onto a radiation-tolerant LEON 3 processor and benchmarked various unsupervised and semi-supervised techniques with respect to their performance, memory footprint, and runtime. Our recent advancements focus on bridging the gap between a proof-of-concept solution and a nearly production-ready system. Mainly, we focused on preparing a semi-automatic pipeline for model training and deployment, experimented with other types of machine learning models, and created a patch for TensorFlow Lite for Microcontrollers (TFLM) which allows integration to the LEON 3 processor while still following the guidelines regarding software safety. Additionally, we incorporated uncertainty quantification (UQ) techniques to provide a more reliable assessment of the black-box model’s outputs.

103 Enhancing Flight Software Development through a Model-Based Approach: A Case Study on Alsat-1B

Developing satellite flight software (FSW) presents considerable challenges, requiring rigorous methodologies to ensure both reliability and efficiency. In this paper, we explore the application of Model-Based Development (MBD) to the periodic operations within the Attitude and Orbit Control System (AOCS) of the Alsat‑1B satellite. Our approach systematically models, simulates, and validates these functions using Unified Modeling Language (UML), Foundational UML (fUML), and Action Language for fUML (ALF). A pivotal aspect of our methodology is the use of ALF as an intermediary layer between the high-level model and the final code generation, ensuring that behavioral specifications are accurately translated into executable code. We evaluate the system’s robustness by simulating various error scenarios, including timing irregularities and state inconsistencies. The results demonstrate that our method facilitates early detection of design issues and supports a more reliable transition from model to code. This work highlights the potential of MBD to streamline FSW development for small satellites, offering valuable insights into enhanced testing and validation practices

108 Instrument Control Unit (ICU) for Multi-Purpose Payloads: A Versatile and Modular Solution

The increasing demand for commercial payloads has driven the development of innovative, high-performance control and data acquisition systems. In this context, the Instrument Control Unit (ICU) emerges as a key component for the efficient control and management of Electro-Optical payloads. Our research presents an advanced ICU architecture that leverages the computational power of the SAMRH71 processor alongside the real-time capabilities of the RTG4 FPGA. This synergy enables the management and processing of large volumes of high-speed data, a critical factor for modern high-resolution observation technologies.
The ICU is designed for both high-performance data acquisition and exceptional modularity and flexibility. Its architecture facilitates integration into a wide variety of space payloads, allowing adaptation to different mission requirements. Key functionalities include TMTC (Telemetry and Telecommand) SpaceWire Interface and High-Speed Serial Link (HSSL) with Platform, Time Synchronization, Power Conditioning and Distribution and Thermal Control, and the management of up to two cameras via SpaceWire and Universal Asynchronous Receiver-Transmitter (UART) interfaces. Furthermore, the system can optionally incorporate a data compression module to reduce downlink bandwidth requirements when handling large datasets from multispectral, hyperspectral, and radar sensors. The unit is also engineered to drive stepper motor mechanisms for critical operations such as refocusing and shutter control, thus enhancing image quality.
A robust power management strategy is implemented by conditioning power from an unregulated primary bus and distributing it effectively across various subsystems, ensuring stable and reliable operation under unpredictable conditions. The ICU supports comprehensive in-flight reprogramming of both firmware and application software, including updates to the FPGA firmware and subsystem firmware. This dynamic reprogrammability enables the unit to adapt to evolving mission requirements and significantly extends the payload’s operational lifespan.
The core hardware components — the SAMRH71 Rad-Hard Microprocessor and the RTG4 radiation tolerant FPGA —complement each other in meeting the demanding requirements of spaceborne data acquisition. The SAMRH71 delivers high computational performance with low power consumption through its internal operating system (FreeRTOS), while the RTG4 provides real-time processing, and high data transfer performance (up to 5 Gbps) via its built-in serdes blocks. Moreover, thanks to the redundant interfaces toward platform and the high quality of components (at least ESCC Class 2 or equivalent), the ICU enhances the robustness of the Payload and its reliability figure.
The ICU has been designed to meet the requirement of three different E.O. Payloads in development at Leonardo Space Business Unit: Very High Resolution (VHR), Thermal Infrared (TIR) and Hyperspectral (HYP). The VHR payload, optimized for high-resolution Earth observation, features a refocusing mechanism to enhance image quality for applications ranging from environmental analysis to precision agriculture. The TIR payload requires high thermal control performance, measurement accuracy and stability. Finally, the ICU is tailored for hyperspectral imaging, providing high data management capability from two cameras. These applications underscore the ICU’s versatility and its ability to serve multiple missions in Earth observation.

133 Efficiently Escaping Low-Level Design in Digital Microelectronics by Wise Auto-Coding of HDLs from High-Level Models

Digital microelectronics for space applications have traditionally been developed at the Register Transfer Level (RTL) through manual process using Hardware Description Languages (HDLs). While this approach has served as a one-size-fits-all solution, recent challenges such as increasing system complexity and reduced times-to-market have motivated the exploration of alternative methods.

This paper focuses on the auto-coding of reliable HDL from high-level models of digital microelectronics, addressing key questions like why, how, and in which space applications engineers are adopting auto-coding tools. Additionally, the paper also provides an overview of the ongoing production of the Handbook for Auto-Coding of HDLs for Space FPGAs, highlighting its main insights and implications for the field.

151 Synthetic Data Generators for Enhanced Space-based Network Traffic Modeling

Synthetic data generators (SDGs) are indispensable tools in telecommunications and satellite communications, providing a means to simulate otherwise hard-to-obtain realistic traffic scenarios for pre-deployment testing and system optimization. This paper introduces a framework for generating synthetic bandwidth demand data by integrating macro-scale and micro-scale approaches. The macro-scale SDG models long-term trends, daily and weekly seasonality, random noise, and occasional spikes over an extended period of time, typically a year. In contrast, the micro-scale SDG captures short-term, minute-level variations within a day or week, adjusted for different application demands such as phone calls, video calls, and video streams. The proposed ensemble SDG merges these scales, producing synthetic datasets that provide high fidelity in both broad and granular temporal views of bandwidth demand. We further extend the model by scaling demand with population density and projecting it onto satellite beam footprints for SatCom applications. This paper details the mathematical formulations, implementations, and theoretical underpinnings of each SDG component, demonstrating their effectiveness and realism through experimentation. The proposed framework supports a wide range of applications, enhancing the ability to plan, optimize, and innovate in the field of (not only satellite) telecommunications.

This paper presents the advances made by GTD in developing systematic guidelines and tools for ECSS Category A flight software production, with specific application to the application software development and qualification for the I-HAB module contributed by ESA to the Lunar Gateway project. The work addresses historical pitfalls in past approaches to Category A qualification, introduces new open-source tools, and demonstrates practical adaptation to diverse computing environments including target processor systems and operating systems infrequently used by the European space industry.

173 SKE: emulation of on-board computer environments in operational simulators

SKE is a software application for general-purpose Linux host servers that allows to emulate the partitioned environment designed for computers on-board satellites running mixed-criticality systems that require time and space partitioning and fault detection and isolation. The benefits of using SKE are manyfold, from helping to develop in Linux environments the mentioned systems that will run on top of the XtratuM/NG (XNG) hypervisor, up to be exploited by operational simulators to run on-board computers faster than real time. In this latter context, this paper shows how SKE is being integrated in the CNES’s KOSMOS framework to provide the on-board computer environment inside a full numerical simulator of a swarm of satellites. SKE is aimed to provide the expected functionality of the XNG hypervisor, offering faster-than-real-time performances when executing the flight software and still keeping a good level of representativity in terms of functional behaviour.

178 Preliminary Design of the Stellar Apps Software Platform for Developing and Executing On-board Applications

The German Aerospace Center (DLR) is developing Stellar Apps, an on-board application platform designed for space missions. Third-party applications and system services are deployed as Apps. These Apps can be executed in isolated environments with configurable access to the spacecraft and its computing resources. This allows users to regularly add, replace, remove, and update Apps to improve the flexibility and reusability of multipurpose spacecraft. Complex applications can be executed and tested in a secure environment, reducing their time to orbit. API-based communication between Apps and hardware allows the Stellar Apps platform to be used on a wide variety of spacecraft, including satellites, rovers, space stations, and entire satellite constellations. Access to commonly used artificial intelligence libraries and accelerators paves the way for future space applications. Stellar Apps provides end-to-end services ranging from development on the ground to deployment of Apps in space. The platform is currently available as a prototype at the German Aerospace Center (DLR) and is planned for an in-orbit demonstration during the second year of DLR's CAPTn-1 mission. This paper presents the preliminary design of the software platform.
