Abstract
In the CubeSat industry, the demand for benign launch environments that can be predicted is continuously increasing, but the current knowledge of CubeSat environments leaves a lot of CubeSat developers without accurate information regarding the environments that their CubeSats will experience. Due to the severe random vibration environments experienced on launch, the industry has already taken strides to provide isolation systems that significantly reduce these levels. While these systems are very successful at reducing loads, many of them are still difficult to accurately predict for any given random vibration specification. Additionally, the demand for larger, 12U CubeSats has increased, while 12U environments have remained relatively unexplored. NLAS isolated transmissibility is compared to the baseline, and an isolated 12U dispenser transmissibility is explored. Each dispenser modeled and correlated to test data to evaluate the efficacy of analysis for each system. Additionally, methods for predicting environments for a given input specification are reviewed and compared.
