Aggiesat6 University Cubesat Ops Prep And Leops, Avery G. Barriga, Garrett M. Stevenson, John F. Connolly

Small Satellite Conference

AggieSat6 (AGS6) is a 6U CubeSat designed and developed by students at Texas A&M University (TAMU) as part of the University Nanosatellite Program (UNP) NS-10 cycle. The mission will demonstrate a space-based radio frequency array for Space Domain Awareness (SDA) applications and collect low-energy electron radiation data to improve existing environmental models. Beginning in January 2025, students at TAMU established mission operations architecture, implemented operator training and certification, and prepared to assume sole responsibility for on-orbit operations. The AggieSat6 bus launched into Low Earth Orbit (LEO) in April of 2026. The AGS6 Mission was supported by the University Nanosatellite Program. …

Promoting Assured Formation Flight Autonomy Onboard Resource Constrained Systems, Ryan Johnson, Maggie Michelsen, Jackson Gardner, Mario Harper, Charles Swenson, Jackson Kulik, Shawn Jones

Small Satellite Conference

Autonomously determining fuel-optimal, formation-keeping trajectories for small spacecraft operating in formation flight is often limited by available processing power. Because SmallSat missions are constrained by size, weight, and power (SWaP), field-programmable gate arrays (FPGAs) are an attractive option for onboard computing. Traditional formation-keeping relies on convex optimization to solve for fuel-optimal burns and burn times; however, implementing these solvers on FPGAs is challenging due to limited board resources.

To address the need for fast, reliable trajectory planning onboard space vehicles, we investigate leveraging machine learning to reduce computational cost for real-time, onboard execution. We propose using a deep neural network …

Propellant-Free Formation Keeping Using Environmental Perturbations In Leo Via Orbital Angular Momentum Vector Matching, Yu Seike, Takaya Inamori, Keita Tanaka

Small Satellite Conference

Small-satellite formation flying enables new mission capabilities.

e.g. MIMO (Multi Input Multi Output) Communication

Challenge: Conventional formation keeping requires thrusters. Small satellites have limited onboard resources.

Motivation 

• Quantum key distribution (QKD) offers provably secure communication regardless of the technology available to potential eavesdroppers.
• Space-to-ground QKD facilitates long-distance key distribution without costly terrestrial infrastructure.
• The Polarization-modUlated Laser Satellite Experiment – Quantum (PULSE-Q) is a 12U CubeSat mission to leverage recent innovations in compact quantum sources and optical communication to achieve space-to-ground QKD.

AggieSat Laboratory (AGSL) is a student-run space program that trains students in systems engineering through hands-on experience in the design, building, testing, and operation of space and space-related systems

AGSL is currently comprised of 107 students, most of whom are undergraduates. Its members work on eight active projects (including a shadow program for underclassmen).

AGSL has demonstrated flight heritage with the deployments of AggieSat2, AggieSat4, and AggieSat6.

CubeSat launches continue to increase yearly, yet over 51% of missions from 2002–2016 failed. Primary faults were often due to power, mechanical, or design issues. Costs still remain high in a market driven by expensive flight-heritage hardware with proprietary designs. In order to counteract such costly practice, Sun Devil Satellite Lab (SDSL) at ASU has developed an open-source, modular 3U CubeSat bus built for low cost reliability. Unlike other bus architectures, SquidSat distributes control across independent microcontrollers linked via a CAN bus. CAN is commanded by the OBC but is capable of independent operation for fault isolation and easier testing. …
