Abstract:

This thesis describes the assessment and analysis performed to characterize the communication subsystem used for command and telemetry transmission in support of the Grissom-1 Mission GMl. The GMl is unique in that it represents the pathfinder for a standardized 6U bus that serves as the basis for future CubeSat missions to host a variety of technical and scientific payloads, as prioritized by the Department of Defense, requiring flight demonstration or access to the orbital environment. Lab-based testing within an anechoic chamber provided link margin data required to characterize the command and telemetry links of the GMl. Experimental data describing the results of each test are also included. The research culminates in a full characterization of the software-defined radio, an analysis of the GMl to MC3 communication interaction, and any limitations revealed as attributable to the 6U spacecraft. Collected data supports an analysis of the limitations inherent to the current GMl communications subsystem configuration as operated at a variety of orbital distances plus recommended augmentations to the MC3 network to support those distances.
