Potential NASA Commercial Applications: Investment by NASA/NSF in SmallSats programs and projects is rapidly increasing. As already identified in previous studies, the scope of these mission increase there will be a corresponding increase in demand for high accuracy Attitude Control System ACS capability. This is especially true for cross formation flying, cross-link communications, and proximity, rendezvous operations, observational data, and onboard experiments. Our goal will be to make available a near-universal low cost enhancement add-on that NASA users from academia to NASA Centers can purchase and easily install between the RWA bracket and a common attachment plate (possibly PCB) that can easily be linked into legacy, or to be developed, ACS controller design (e.g. PI or PID) as to substantially increase pointing accuracy of the SmallSat/CubeSat platform.
