Satellite Attitude Dynamics & Control System (ACS) Testbed
The Satellite Attitude Dynamics & Control System (ACS) Testbed 2015 Capstone Design Project focused on developing a simulator/test-bed to test ACS theories, algorithms, and software. The project aimed to simulate various spacecraft and featured full 360-degree motion, configurable inertia, re-configurable reaction wheels, and automatic balancing capabilities. Out-of-the-box thinkers with expertise in mechanical design, MATLAB interface, and controls/systems were sought for the project.

Satellite Attitude Dynamics & Control System (ACS) Testbed 2015 Capstone Design Project
State of the Art? 3-D is not always fully 3-D There is usually a limiting axis that is not fully exploitable Real spacecraft use all axes simultaneously Every new algorithm, SW or HW must be tested and verified before anyone is willing to fly it. Every S/C ACS can be represented by an Inertia Matrix and Momentum Exchange Configuration (Reaction Wheels) Scaling is important, but balancing is critical NPS Air Bearing.

2015-2016 Capstone Project Goals Design a Simulator/Test-bed capable of simulating other spacecraft in order to test ACS theories, algorithms, and/or software Full 360 motion about any axis Configurable inertia in order to simulate any particular spacecraft 4 Reaction Wheel re-configurable ACS Automatic balancing of the air bearing setup Sized to accommodate a 3U CubeSat frame
Who do we need? . Out of the box thinkers 3D is harder than 3 x 1D Other have done similar but not for the same purpose or level of fidelity EyaSat Concept is for classroom demo purposes only Mechanical Design in both large scale (3U) and small scale (4 RW & moving masses) MATLAB interface & data collection/processing Controls or Systems like emphasis role Needed for the Automatic balancing element. Know any SE majors who need a capstone? EyaSat Concept, https://youtu.be/6YG7q7sqfTM
