A Feasibility-Aware Attitude Trajectory Planner For Small Satellites, Patrick Mckeen, Niclas Scheuer, Kerri Cahoy

Small Satellite Conference

Spacecraft attitude control traditionally requires extensive per-mission engineering—hand-tuned gains, mission-specific mode logic, and conservative operating envelopes—that breaks down when on-orbit conditions deviate from ground assumptions. This is especially costly for small satellites, where limited ground support makes autonomous adaptability essential. We present a feasibility-aware attitude trajectory planner that replaces this hand-engineered stack with continuous planning from a digital twin: less a new feedback law than a different division of labor, in which the mode logic, gain tuning, and desaturation a conventional ADCS builds as separate pieces are instead absorbed into a single optimization.

Built on the ALTRO trajectory optimization algorithm, …

Shining A Spotlight On Maritime Dark Traffic, Alex Da Silva Curiel, Darren Jones, Rob Knight, Rupert Taylor, Leo Jofeh, Sir Martin Sweeting, Per Atle Våland, Simon Flack, Patrik Mandelin, Håkon Heier

Small Satellite Conference

The ability to support Maritime Domain Awareness from space using Synthetic Aperture Radar (SAR) has been successfully demonstrated in the past, however practical challenges in achieving the necessary area coverage, temporal coverage and spatial resolution for a practical system has eluded wider adoption. Yet demand for Maritime Surveillance has increased in recent years, to protect important maritime energy and communications infrastructure, fisheries, and maritime reserves, and especially for maintaining national security and territorial integrity. A novel approach to the SAR payload design solves these challenges, and smallsat technologies have also matured to the point where a High-Resolution Wide-Swath (HRWS) system …

High-Torque Reaction Wheels For Agile Small Satellites, Thomas Brunsgaard, Matt Carton, Kearney Lackas

Small Satellite Conference

Blue Canyon Technologies has developed a high-torque reaction wheel (RW) product line to meet the growing attitude control demands of next-generation small spacecraft. As small satellites expand into missions requiring rapid retargeting and precise pointing, spacecraft agility is foundational to mission performance. More targets equal more data collection, translating to greater mission insight and revenue generation. 

This paper describes Blue Canyon’s approach to product line architecture that enabled rapid development and deployment of high-torque reaction wheels across multiple size classes. The high-torque variants deliver 0.5 Nm of torque, representing a 2X increase over standard configurations with 60% of the baseline …

Development Of Piezo Fast Steering Mirrors For Fso Inter-Satellite Communication, Frank Claeyssen, Arnaud Gilson, Thomas Maillard, David Ferris, Xavier De Lepine, Oliver Sosnicki, Jocelyn Rebufa, Clément Cote, Francis Bortolaso, Pascal Mexe

Small Satellite Conference

To allow faster communication between satellites, Radio Frequency (RF) links are being replaced by laser optical links, often called Free-Space Optical Communication (FSO). Each satellite embeds several optical communication terminals (OCT), each one needing two Fast Steering Mirrors (FSM) for laser beam fine and fast steering. Thus, for some giant constellations, the total number of FSM can reach up to 100 000 FSM. This New Space market induces not only technical challenges, such as good SWaP, but also industrial challenges, in particular reproducibility, cost-effectiveness and low cost of ownership vs Orbit segment. To address these various FSM needs, CEDRAT TECHNOLOGIES …

Modeling Of Supersonic Wave And Shock Propagation Using The Lattice Boltzmann Method, Timothy P. Schroeder

Beyond: Undergraduate Research Journal

The lattice Boltzmann method (LBM) has emerged as a mesoscopic alternative to traditional Navier-Stokes solvers for modeling fluid dynamics offering advantages in computational efficiency, parallelization, and handling of complex boundaries. Despite these strengths, accurately reproducing compressible, shock-driven phenomena remains challenging. This study investigates the performance of LBM in simulating the Sod shock tube problem, a classical benchmark for compressible flow-using both single and double distribution function formulations across one- and two-dimensional lattice stencils. A MATLAB-based solver was developed to model the flow under isothermal conditions and compared to the analytical solution using the L2 norm error. The one-dimensional models achieved …

Optimizing Ball‐Milled Composites For Fast Energy Release Under Shock Compression, Siva Valluri, Edward Dreizin, Dana Dlott

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters that govern microstructural features such as intraparticle voids and fuel-oxidizer mixing, and the resulting inhomogeneous shock reactivity of individual particles. To present our approach, we used a model composition 8Al⋅3CuO, previously optimized for combustion. We milled powders and prescreened different prepared batches using differential scanning calorimetry (DSC) to rule out batches with significant pre-reaction. Then …

831sat: A Cubesat Subsystem Platform For Space Systems Development Education, Dominic S. Fucile, George Lordos, James Dingley, Kerri Cahoy, Paul Fucile

Small Satellite Conference

The CubeSat standard has become one of the most popular frameworks for co-curricular and extracurricular student satellite projects, yet its integration into formal curricula for space systems engineering remains limited.

Accessibility concerns:

• Students encountering satellite design for the first time face a learning curve when working with flight-representative hardware.
• Time constraints of undergraduate semesters limit the technical depth covered in a single course.
• Existing educational platforms often lack subsystem flexibility and fidelity needed to deliver an authentic systems engineering experience.

Presented is the 831Sat, a custom single board platform that provides core satellite subsystems:

• Central Processing Unit
• Electrical Power System …

Small Satellite Conference

Aerospace developed a warm gas water vapor propulsion system for the OCSD-A mission in 2015 and redesigned it for the AeroCube-10 mission in 2019. Those were single nozzle systems. The 2019 mission performed reliably so this design is an evolution to 5 thrusters. Also new is that the main tank is additively manufactured aluminum so that tubing can be embedded and thermal management is easier.

Mission success ultimately depends on reliable telecommand and telemetry links between spacecraft and Earth. For small satellites operating under tight power, size and link margin constraints, a technically robust and regulation compliant ground station is a mission critical enabler rather than an afterthought.

This poster presents a case study of a semi automated UHF ground station designed, built and commissioned by HEX20 in Thiruvananthapuram — one of the earliest privately owned and operated satellite ground stations in India — covering the hardware signal chain, the tracking and decoding software stack, integration and calibration, and the regulatory path to operation.
