  • Streamlining Verification & Validation of GNC Subsystems using NeXosim: an Open-Source, Rust-Based Discrete Event Simulator.

    Over the past decades, the complexity of both commercial and scientific space missions has steadily increased. As new classes of space missions are undertaken, and their technical and programmatic objectives become increasingly ambitious, more advanced spacecraft architectures are developed to support them. In-Orbit Servicing (IOS) missions constitute a particularly relevant example of space endeavors that…

  • 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…

  • A Modular Open-Source ADCS Framework for Small Satellite Development and Testing

    Advanced attitude determination and control (ADCS) techniques are often difficult for small satellite teams to adopt due to tightly coupled implementations and the need to rapidly evaluate alternative architectures. Evaluating prospective ADCS options may require significant modification of existing code for specific actuator combinations, sensor hardware, orbits, mission goals, and control laws. Existing options are…

  • Design, prototyping and mechanical testing of a trifilar deployable helix antenna for CubeSat applications

    Deployable helical antennas are often used in space in the VHF and UHF transmission bands because they provide high gain, large bandwidth, and high directivity with circular polarization while maintaining relatively low fabrication complexity. Usually, these deployable antennas are composed of a main foldable, non-conducting isolated structure which acts as the helicoid support for the…

  • CubeSat ISR Constellation Mission Tailoring

    This paper presents a modelling framework for Intelligence, Surveillance & Reconnaissance (ISR) CubeSat constellation combining optical payload and Software Defined Radio (SDR). The concept satellite is 8-16U depending on the payload resolution and presence of warm-gas propulsion allowing for orbital changes and station keeping extending the operational time. Deployed in 500-km Sun-Synchronous Orbit (SSO), the…

  • Space weather forecasting using SARIMA

    Solar fluxes and geomagnetic activity influence the temperature of the air, and consequently the density. These phenomena are hard to predict because of their highly nonlinear and stochastic nature. However, they have significant effects on LEO space missions and orbital decay time estimations, since air drag is one of the major perturbations in this region.…

  • The Final Barrier to High-Performance Computing in Space: Architectures for Mitigating Catastrophic Radiation Effects

    The increasing ambition of commercial and institutional space missions is driving demand for onboard computing capabilities far beyond traditional spacecraft avionics. Applications such as orbital data centers, large satellite constellations, autonomous mission operations, and real time data processing increasingly depend on high performance GPUs, advanced processors, high density solid state storage, and complex commercial electronic…
