Attitude Determination And Control System With Variable-Speed Single-Gimbal Control Moment Gyroscopes For Nanosatellites, Jordan H. Hsieh, Thomas Yen, Sam Lee, Austin Chang, Luke Hou

Small Satellite Conference

This paper presents a novel Attitude Determination and Control System (ADCS) utilizing Variable-Speed Control Moment Gyroscopes (VSCMG) tailored explicitly for nanosatellites. The VSCMG was realized by spherical motor technology, in which a patented magnetic field design controls the inner rotor and gimbal. Because of the characteristics of the control moment gyroscope, the proposed ADCS offers improved attitude maneuverability and reduced power consumption, addressing the limitations of traditional ADCS solutions for nanosatellites. Furthermore, the adoption of spherical motor technology shrinks the VSCMG into a smaller form factor, which allows the VSCMG to be fitted into a nanosatellite. This research paper introduces …

Multidimensional Analysis Of Future Leo Environment & Associated Challenges For Space Sustainability, Nana Gordon, Dylan Reeves

Small Satellite Conference

For 66 years the space sector has experienced tremendous growth. More than 13,000 satellites have been successfully launched into orbit, of which 4,600 are smallsats launched in the last decade alone. Untapped market potential and the anticipation of ongoing growth in smallsat launch rates is undisputed as early constellations implement replenishment cycles and budding start-ups and national security programs are deployed at scale. Given this growth, in the presence of existing satellites and the 130+ million debris objects on-orbit, satellite operators are faced with the challenge of operating in a complex environment and addressing space sustainability.

Designing A Model-Based Systems Engineering (Mbse) Template For Satellites, David Walker, Dan Christensen, Brad Mercer, Gavin Payne

Small Satellite Conference

The goal of this project has been to digitally transform SDL systems engineering methods for scoping small satellite missions, developing system architectures, documenting the engineering solution, and verifying design solutions from being document-intensive (gathering non-transformable information in discrete, disjoint documents) to being model-based (employing cohesive, traceable, transformable graphical models).

We have produced a set of models that give satellite development programs (and any "model-based" program) a head start that enables the modeling effort to drive the systems engineering process instead of catching up with a document-driven design. We plan to use these models to develop, train, and encourage consistent modeling …

Simple Scheduling Algorithm For Growing Constellations, Lauren Fitzgibbon, Chris Shaffer

Small Satellite Conference

As the number of satellites in orbit grows, satellite constellation operators must consider better ways to balance the usage of ground assets. In general, ground asset availability does not grow linearly with the number of satellites launched, so alternative approaches to divide usage amongst a limited number of ground assets are required. While advanced techniques exist to manage these factors, they are often not practical for small and growing constellation managers.

The authors have developed a computationally simple method for dividing available antenna time between satellites, considering available access windows. This was designed to adapt to any number of heterogenous …

Do Multisat Constellations Make It Easy For The Bad Guy?, Brandon Cesul, Edgar Ryan

Small Satellite Conference

With the United States moving toward fielding "massive multi-satellite constellation" architectures of small satellites for national security missions (to include dual-use commercial services), a radical change in the strategic calculus associated with space defense and space superiority is forthcoming. While many aspects of natural defenses of massive multi-satellite constellation architectures have been presented by U.S. government advocates such as the Space Development Agency, acquisition executives and strategic thinkers must consider additional factors for potential vulnerabilities and some potentially non-intuitive strategic impacts. Here, we specifically focus on the space situational awareness needs of potential attackers when considering conterspace actions against the …

The Arkisys Port Module: An Orbital Platform For Hosted Payloads In Low-Earth Orbit, Rahul Rughani, David A. Barnhart, Dan Lopez

Small Satellite Conference

Advances in Small Satellite technology combined with the availability of low-cost rideshares to Low-Earth Orbit (LEO) have led to an increasing number of space missions. However, the underlying technology for small payload missions has been relatively constant over the past two decades: CubeSat form factor platforms for free-flying missions in LEO. Arkisys is working to change this, and allow a wider variety of payloads to reach LEO which don't include an immediate free-flying requirement. This platform is called The Port, and is an autonomous long-duration orbital platform for a multitude of uses, including hosting payloads in LEO.

Currently, avenues …

Using Space Domain Awareness Tools And Electric Propulsion To Evade Space Debris, Patrick R. C. Neumann, Steven Despotellis, Hervé Astier

Small Satellite Conference

As more spacecraft use electric propulsion for altitude change, constellation management, and end-of-life disposal, attention is being given to other use-cases such as debris avoidance. While the growing population of all-electric GEO satellites and all-electric LEO megaconstellation satellites have demonstrated successful collision avoidance to date, they either operate in orbits with a smaller debris population (e.g., the GEO satellites) or have power budgets scaled to support high communications throughput which can be applied to propulsion systems as needed[1]. There has been doubt expressed that small spacecraft of more limited power supplies can host electric propulsion systems with sufficient thrust to …
