Sponsor: Stephen Robinson, Ph.D. Mechanical & Aerospace Engr One of the few methods of simulating spacecraft dynamics on Earth is on an air bearing table. On an air bearing table, an air bearing creates a small cushion of air between a model spacecraft and the table, enabling low-friction planar motion and simulating spacecraft dynamics. This provides 3 degrees-of- freedom: 2 translational and 1 rotational. The Human, Robotics, Vehicles Integration and Performance Laboratory (HRVIP) aims to test attitude determination systems using this method. However, attitude testing on an air bearing requires a highly flat and smooth surface, ensuring gravitational effects do not interfere with the CubeSat's dynamics. The glass surface used for previous experiments encountered many problems maintaining a flat surface. We researched two alternative materials that would allow for more accurate measurements, while meeting specified flatness and roughness requirements. While we found that precision epoxy could form a flatter surface, grade B granite would be a more cost-effective solution while still meeting our flatness and roughness requirements. The development of this in- house testing environment provides an accessible and cost- effective method for performing CubeSat research. Furthermore, our trade study analysis is useful for other universities and institutions that need to conduct similar spacecraft research.
