Session
Technical Session X: Attitude Determination & Control
Abstract
The NASA Small Spacecraft Technology Initiative was among the first of the high performance, low cost spacecraft programs. It was NASA's postulate that by leveraging U.S. technology investments and minimizing customer management oversight, significant reductions in cost and schedule could be realized, while advancing the state of the art in spacecraft performance. Use of the latest in sensor, processor, and structures technology enabled the SSTI Lewis Guidance, Navigation and Control Subsystem to significantly improve its pointing capabilities over most lightsat programs. The combination of vastly reduced customer oversight, extensive subsystem heritage from previous programs, and the flexibility to use in-house, high reliability design and testing practices allowed the subsystem to complete under the original budget, and in less than two years. Compared with other high quality LightSats, the SSTI Lewis GNCS has superior performance, was completed in less time, cost less to produce, and is of equal or higher quality.
The SSTI Lewis Better, Faster, and Cheaper Guidance, Navigation, and Control Subsystem
