An Innovative Approach for Validation of Large Space Structure Controls - Structures Interaction Technologies (CSI-SAT)

In-space flight experiments are required to validate dynamic response and control characteristics of ground experiments and their models in order to support future DoD/NASA Large Precision Space Structures missions. This paper, based on an ongoing Small Business Innovation Research (SBIR) Program with the Air Force Astronautics Laboratory, will describe an innovative approach for space flight experiments to demonstrate and validate Control-Structures Interaction (CSI) technologies and methodologies based on emerging Small Satellite Initiatives. The current trends in DoD/NASA missions, the existing CSI ground experiments and the planned space experiments are presented. A concept is identified for a Control-Structures Interaction satellite (CSI-SAT) and compatible launching platform necessary for performing affordable on-orbit testing of CSI technologies which cannot be accommodated in ground tests. Selected technologies and technology suites (integrated at subsystem level) for space testing are identified.
