USNA Standard CubeSat Bus Project Overview
USNA's CubeSat project involves launching two satellites, USNA-14 and USNA-15, completing in May 2016. The mission objectives focus on building a CubeSat in a 90-day timeframe with various systems like Command and Data Handling, Electrical Power System, Communications, and Attitude Determination and Control. The goal is to develop a high-capability, modular hardware and software standard bus for use in various missions, emphasizing functionality and easy reconstruction through documentation. The project also includes activities such as leveraging current satellite architecture, learning from integration and testing, and applying knowledge to new designs. The project aims to demonstrate the functionality of the CubeSat through various concepts of operation like the StaCSat payloads and small spacecraft propulsion integration.
