Pointing Error Metrics Workshop Part 3: Requirements Definitions, Flowdown, Interfaces, Model Updates

The purpose of this Workshop is to inform practicing GN&C engineers, system engineers, and payload instrument engineers of advanced methodologies for analyzing the pointing performance of spacecraft and writing unambiguous pointing requirements that are relevant to performance of optical payloads, especially payloads with stringent pointing stability and jitter requirements. Another purpose of this Workshop is to provide techniques that can help attitude control and spacecraft system engineers understand the relationship between the Optical Transfer Function (OTF) and pointing errors. In this Workshop, rigorous mathematical definitions of displacement, smear, and jitter will be presented, and smear and jitter metrics incorporating key elements of optical engineering will be derived.
