Enabling Software-Defined Satellites with Edge AI
Software-Defined Satellites (SDSs) enable spacecraft to evolve on orbit through software, moving beyond fixed-function architectures toward adaptable, multi-mission platforms. Software-defined radios and reconfigurable sensors and onboard compute systems provide foundational flexibility, while the integration of artificial intelligence at the edge is critical to achieving true operational autonomy. This presentation examines how AI-enabled onboard processing allows…

Decentralized Operational Framework for Autonomous Space Traffic Management in High-Drag VLEO Environments
The rapid expansion of Very Low Earth Orbit (VLEO) constellations introduces significant complexities in orbital maintenance due to non-conservative forces, primarily stochastic atmospheric drag. Traditional centralized Space Traffic Management (STM) architectures, which rely on batch-processed updates and human-in-the-loop decision making, are increasingly incapable of managing the high-frequency station-keeping maneuvers required in these altitudes. This paper…

Semi-Autonomous Reconnaissance Satellite: A Laboratory Demonstration of End-to-End On-Board Mission Autonomy
Real-time satellite responsiveness to user requests from the field remains largely unavailable in current space systems. Such capabilities are typically restricted to low-altitude airborne platforms, primarily due to limited satellite communication bandwidth, intermittent ground contact, and the reliance on ground-based mission planning. Enabling true responsiveness requires a paradigm shift toward highly autonomous satellites, in which…

In-Orbit Experimental Validation of Autonomous Operations within the AIX Satellite-as-a-Service Framework
As Low Earth Orbit (LEO) constellations continue to scale, traditional ground-centric operational paradigms struggle to meet increasing demands in latency, flexibility, and operational cost. The AIX (AI-eXpress) mission series addresses these limitations by introducing a service-oriented satellite architecture that enables dynamic in-orbit resource usage and application deployment. This paper presents the in-orbit experimental activities performed…

Catalysing Next Generation Solutions with Scalable Model-Based Software
Small satellite missions increasingly rely on software-defined payloads, onboard data processing, and automated mission operations, to meet performance, responsiveness, and cost constraints. In practice, payload software development, integration and test (I&T) and operations are often supported by fragmented toolchains spanning flight, ground, and payload domains, leading to duplicated effort, reduced reusability and increased operational risk.…

Intelligent Orchestration for Hosted Payload Architectures in Satellite-as-a-Service Missions
The rapid growth of the “Satellite-as-a-Service” market and the rise of In-Orbit Demonstration/Validation (IOD/IOV) missions have accelerated the demand for flexible hosted-payload architectures. Integration of third‑party payloads onto a host bus introduces complex challenges in resource contention, interface standardization, and operational risk management. Traditional integration of third‑party payloads onto a host bus suffers from resource…

Mission-level differential drag control for formation flying of 6U CubeSats through automated management of rule-based and power-budget modes.
The operational success of inter-satellite laser link (ISL) missions in CubeSat constellations depends on the strict management of conflicting requirements: energy harvesting, high-precision payload targeting, and orbital maintenance. This paper presents an automated onboard mission logic designed to manage the relative distance of a two-satellite 6U in formation flight (ranging from 100 km to 1000…

Beyond Monolithic Ground Systems: Building Adaptive, Interoperable Ecosystems for Commercial Space
Modern space missions are becoming increasingly diverse, rapidly evolving, and commercially driven. As a result, mission operators face an operational landscape where no single ground system can meet all requirements throughout the mission lifecycle. Each mission requires a unique combination of capabilities, including command and control, planning, ground station orchestration, flight dynamics, collision avoidance, and…

AI-Based Navigation for Lunar Satellites in VLLO
This paper presents the design and preliminary validation of the Lunar Intelligent Navigation via Neural Architecture (LINNA) payload, a technology demonstration integrated into the SelenITA mission—Brazil’s first lunar CubeSat. The experiment is motivated by the future needs for autonomous state estimation in the Very Low Lunar Orbit (VLLO) regime, where Mascon-induced gravitational anomalies challenge traditional…

FOCUS: Free-space Optical Communications Unit for Satellites
Laser and optical communication terminals offer tremendous opportunity for high-speed (>1 Gbps), highly-secure, inter-satellite and satellite-to-ground global communications. Traditionally, high size weight and power (SWaP) requirements have created challenges in realising COTS products, as well as, the application of such devices in small satellites such as CubeSats. A academic-industry consortium led by Northumbria University have…
