Self-Referencing Positioning System

ABSTRACT: The proposed SBIR work is centered on the integration of Ascentia Imagings AccuArc ultra-precision angular measurement sensors systems and a handheld NDE tool.In operation, one or more AccuArc receivers will be integrated on a NDE tool and a collection of Tx will be mounted at known locations on an aircraft.As the operator moves through the measurement volume as long as at least two Tx are in the FOV of the AccuArc Rx, the system should be able to estimate the 6 DOF orientation of the NDE to < 1mm.As the angular precision of the AccuArc is determined by the detected SNR, placing more Tx or using higher power Tx enable orientation precision to be independently specified for particular system configurations.Depending on the specific operational requirements, for highest possible orientation precision with the fewest components it may be desirable to consider use of non-eye safe Tx.Proper training and/or potential eye protection for the operator could ensure health and safety.; BENEFIT: The anticipated commercial results of Phase 1 will lead two important outcomes:A new software tool to help us and our customers perform tradespace analysis for their systemsA clear path to Class I, Division 2, and CE / ATEX certification for our products, which also means ruggedized systems for our industrial customers
