Advanced Filtering Techniques Applied to Spaceflight

Company: IST-Rolla Agency/Program/Year/Phase: NASA / SBIR / 2011 / 2
Abstract: IST-Rolla developed two nonlinear filters for spacecraft orbit determination during the Phase I contract. The theta-D filter and the cost based filter, CBF, were developed and used in various orbit determination scenarios. The scenarios were application to low Earth orbit,… more

Novel Tool Wear Monitoring of Cutting Tools Using Neural Network based Observers

Company: IST-Rolla Agency/Program/Year/Phase: DOD / SBIR / 2011 / 1
Abstract: ABSTRACT: This proposal seeks to develop a novel tool wear monitoring technology using a neural network-based observer. In this methodology simple models of the wear process and another related machining process, such as force, are developed. The model development does not require lengthy analysis… more
