Distributed Avionics As A Foundational Architecture For Cubesat Constellations And Swarms, Aaron S. Swagei, Ali Guarneros-Luna

Small Satellite Conference

Motivation

CubeSat constellations and swarms require spacecraft that can tolerate subsystem faults without relying exclusively on a single centralized flight computer. Distributing sensing, control, and fault-management authority can improve containment and enable graceful degradation.

Objective

Develop and experimentally evaluate a distributed CubeSat avionics architecture in which subsystem nodes retain local fault-management authority while an F´-based OBC provides mission-level coordination.

The FlatSat is used as a representative spacecraft-level building block for future constellation and swarm architectures.

A Proposed Development Process For A Hardware-In-The-Loop Testing System For Cubesat Components, Vahini N. Patel, Victoria Coverstone

Small Satellite Conference

Hardware-in-the-loop testing systems, commonly known as FlatSats, are testbed systems in which spacecraft subsystems, such as the onboard computer (OBC), power system, attitude determination and control system (ADCS), and communications, are laid flat and interconnected as they would be in an actual spacecraft. This arrangement gives easy access to each subsystem, enabling hardware and software testing and troubleshooting without risking fully assembled flight hardware.

FlatSats are widely used throughout the aerospace industry, from government agencies like ESA and NASA to private companies and university research labs, due to their versatility in enabling parallel development. This accelerates timelines and reduces …

Power Simulation Framework For Korucusat-2 Using Freeflyer, Sahil Singh, Annabel Rong, Mukund Karthikeyan

Small Satellite Conference

A FreeFlyer-based power simulation was developed for KORUCUSAT-2, a low Earth orbit CubeSat designed to monitor silicon-anode battery behavior in space. The spacecraft model uses body-mounted solar panels with five modules on each of the +X, -X, +Y, and -Y faces. The simulation integrates orbital propagation, Earth shadowing, Sun-incidence angle, ground-station visibility, mode-dependent subsystem loads, and battery-state propagation to estimate electrical margin. Battery watt-hours and normalized state of charge are updated at each 30 s step so that critical, low-power, operations, and transmission modes can be evaluated against stored-energy limits. The framework provides a traceable prelaunch test bench for power-system …

Micro-Servicer Swarms For Responsive Smallsat Sustainment: The Sdaw Mothership Architecture, Wanjiku Chebet Kanjumba

Small Satellite Conference

The Challenge:

Sustaining The Mega-Constellation Era: LEO has shifted from a sparse domain into critical global infrastructure. With thousands of satellites on-orbit and tens of thousands more planned, sustainability is no longer guaranteed by launch activity alone; it depends on the ability to service, repair, and responsibly dispose of assets at scale.

• 7,500+ operational satellites in LEO (2024); 50,000+ projected within a decade
• 1,500+ trackable fragments from the 2021 Russian ASAT test; 1,700+ Starlink avoidance maneuvers followed
• ≥ 5 / yr large debris objects removed from LEO yearly to stabilize it (Liou & Johnson)

The Servicing Gap: MEV, OSAM-1, and …

A Cubesat-Based Data Collection Architecture For The Catarina Constellation: Complementing Legacy Brazilian Data Collection System With Lora, Vitória Beatriz Bianchin, Carlos Augusto Porto Freitas, João Cláudio Elsen Barcellos, Gabriel Mariano Marcelino, Talita Sauter Possamai, Eduardo Augusto Bezerra

• The constellation aims to expand the Brazilian Satellite Data Collection System (SBCD) by evaluating new communication technologies, enabling a gradual modernization of the country’s environmental monitoring infrastructure.

Advanced Ai Deployment On Smallsats: A Mixed Precision Approach To Onboard Perception And Fpga-Gated Inference, Margaret Michelsen, Jackson Gardner, Shawn Jones, Jackson Kulik, Mario Harper

Small Satellite Conference

MOTIVATION:

SmallSats are asked to make time-sensitive calls (vessel detection, cloud filtering, debris tracking) but CubeSat-class compute is starved for power, memory, and radiation-tolerant silicon.

Most missions still downlink raw imagery for ground processing, costing hours-to-days of latency and scarce bandwidth. Running inference onboard means solving two separate problems:

• When to run inference: compute and power budgets can’t tolerate a neural network firing on every frame.
• Whether it fits when it does run: the model has to live inside a memory and compute envelope measured in megabytes, not gigabytes.

Helio: Ai Solar Weather Forecasting For Proactive Small Satellite Constellation Response, Kylie Nager, James Kirk, Cagri Kilic

Small Satellite Conference

Challenge:

Small satellite constellations in Low Earth Orbit (LEO) operate in an environment directly exposed to space weather while providing communications, remote sensing, positioning, and other critical services. Geomagnetic storms heat and expand the thermosphere, increasing neutral density, atmospheric drag, and orbital decay. These effects are especially hazardous during post-deployment and orbit-raising operations when satellites remain at low altitude with limited propulsion and recovery margins.

Operational Gap:

NOAA Space Weather Prediction Center products provide essential situational awareness, but satellite operators must still translate environmental forecasts into spacecraft-specific decisions. This translation can introduce operational delay particularly when protective actions must be …

Demonstration Of Integrated Operation Plan Automation For Cubesat Missions, Riki Nakamura, Shunichiro Nomura, Akihiro Ishikawa, Satoshi Ikari, Ryu Funase, Shinichi Nakasuka

Small Satellite Conference

Small satellites, especially CubeSats, are often operated with tight resource margins and small teams. Generating, managing, and validating operation plans under coupled power, thermal, attitude, and communication constraints is labor-intensive and error-prone when done manually.

This work presents an integrated ground-operations automation framework demonstrated on two CubeSat missions.

Development Of A Design Tool For 3d-Printable Cold Gas Thruster Systems For Nanosatellite Missions, Mikolaj Szyszka, Katherine Smith

Small Satellite Conference

Currently, there are 5219 Nanosatellites and CubeSats in orbit [1]. A decade ago, this number was only 800 [1], with forecasts predicting a total of 14,000 small satellites in orbit by 2033 [2]. However, out of the ones that are currently operational, only about 5% are equipped with a propulsion system. Omitting the electric and classified thrusters, cold gas systems are the most popular due to their simplicity and ease of operation. This shows a general lack of manoeuvrability and agility within small satellites in orbit. The proposed C.O.N.E tool aims to bridge the gap between nanosatellite manufacturers and simple …

Development Of Low-Cost And Mobile University Ground Stations, Michael Cargill, Matthew Watson, Patrick Bailey, Jacob Boutin, Wout De Backer

Small Satellite Conference

Recent years have seen a deluge of university-class small satellite missions, driving an increase in demand for ground stations. SatNOGS is an open-source network of ground stations allowing users to schedule observations on each others’ hardware. Most stations are fixed in-place. Mobile stations lack endurance or are high cost. There is a gap for a low-cost option for groups needing mobility.

Experimental And Analytical Investigation Of Low-Power Resistojet Performance For Small Satellites, Ryan Mcpherson, Daniel Kichma, Nathan Paes, Benoit Larouche, Robert E. Zee

Small Satellite Conference

• Small satellite missions increasingly require propulsion systems that can deliver meaningful maneuverability within tight limits on mass, volume, and power.
• Water resistojet thrusters are attractive for this class of spacecraft because they are simple, nontoxic, and compatible with typical small satellite power budgets, but achieving efficient performance at low power remains challenging.
• This work addresses that gap through coupled thermo-fluid modeling, parametric trade studies, and experimental characterization of low-power water resistojet prototypes using a low-cost vacuum testbed.

Measuring Space Weather Through Nitrogen-Vacancy Diamond Quantum Magnetometry: A Cubesat Mission Exploration, Patrick Bailey, Alberto Diaz, Jacob Boutin, Austin Downey, Wout De Backer

Small Satellite Conference

1. The Challenge

• Solar weather is constantly changing with adverse effects on earth and the space around it
• Solar flares cause communication blackouts
• Coronal mass ejections can damage satellite hardware, and cause geomagnetic induced currents that can damage the power grid
• Difficult to measure these effects in real-time

Project Minerva: High-Altitude Weather Balloon Cubesat Research Platform, Gannon English, Gabrielle Guirguis, Jose Murphy, Lena Wang, Ethan Yemm

Small Satellite Conference

Minerva is an undergraduate student-led high-altitude balloon (HAB) platform developed to provide repeatable, low-cost, and flight-proven testing of experimental payloads and communications systems in near-stratosphere environments.

Minimum Variable Speed Control Moment Gyros (Vscmg) Cluster Sizing For Full Three-Axis Smallsat Attitude Control: A Numerical Study, Khang Nguyen, Christopher Damaren

Small Satellite Conference

Small satellites demand high-resolution imaging, optical inter-satellite links, precision science — demand agile, accurate attitude control under tight mass, volume, and power.

Momentum-exchange actuators are the standard propellant-free solution:

• Reaction wheels: precise, but low torque authority
• CMGs: high torque, but singularity-prone
• VSCMGs: variable wheel speed and gimbal angle → high torque, added DOFs for singularity avoidance, dual RW/CMG operation

The gap: VSCMG research has focused on 4-unit pyramid clusters, whose redundancy costs actuator count, volume, and power — resources SmallSats can least afford. The minimum cluster size for practical three-axis control is not well established.

Multi-Satellite Optical Link Scheduling With Direct Nonlinear Attitude Planning, Leif Nelson, Yung-Jai Pomeroy, Daniel J. Garcia

Small Satellite Conference

The Problem:

Low Earth Orbit (LEO) constellations increasingly rely on Optical Inter-Satellite Links (OISL) to route data across dynamic satellite networks. As satellites move through their orbits, communications continuously change due to line-of-sight constraints, link quality variations, and spacecraft pointing limitations. Traditional routing approaches often consider network optimization separately from spacecraft attitude control, creating a disconnect between planned routes and physically achievable communication links. This work addresses the challenge of simultaneously generating communication routes while validating that satellites can physically point toward their assigned target. The result is an end-to-end framework that integrates network planning, optical link feasibility, and spacecraft …

Nebulous: Applying Genetic Algorithms To Design Next-Generation Satellites For Drag Resilience, Rick Marcusen, Adrian Bryant, Julie Rolla, Max Foreback, Evan Imata, Emily Dolson, Kyle Helson, Marcin Pilinski, Anselmo C. Pontes, Jonathan Sy, Joey Wagner, Scott Palo

Small Satellite Conference

Very Low Earth Orbit (VLEO) is a region of space between ~150-400 km that is becoming increasingly valuable for operators of large satellite constellations. VLEO's proximity to the Earth enables improved technical performance, such as higher surface image resolution and lower communications latency, as well as less expensive and more frequent launch opportunities. However, one significant disadvantage to operating in VLEO is the increased effects of aerodynamic drag, which can reduce a mission's lifetime and decrease a spacecraft's position accuracy. To address this, we introduce NEBULOUS, a genetic algorithm-based design tool that evolves spacecraft geometries through generations of mutation and …
