Applying Internet Of Things Principles To Spacecraft, Brian K. Dixon
Theses and Dissertations
This thesis proposes the adaptation of the IEEE 1451 Transducer Electronic Data Sheet (TEDS) for usage in spacecraft subsystems. In the 1990s, TEDS initially were developed as a standardized method to provide metadata required for the operation of a transducer by a microcontroller or data acquisition device. The metadata provides information that identifies and documents key characteristics of the transducer, thereby facilitating plug-and-play interoperability within a system and across networks. An overarching goal of this thesis is to make a case for adapting and extending the TEDS concept as a means for self-describing critical physical components of a CubeSat nanosatellite. …

Theses and Dissertations
Space systems require materials with superior stiffness to weight ratios to provide structural integrity while minimizing mass. Additive manufacturing processes enable the design of metamaterials that exceed the performance of naturally occurring materials in addition to allowing the integration of non-structural functions. This research explored the use of a high stiffness, high density, small melt pool track width AM material, Inconel 718, to enable the production of metamaterials with finer features possible than can possibly be created using a lower density aluminum alloy material. Various metamaterials were designed utilizing thin wall triply periodic minimal surface infilled sandwich structures. The performance …
