Measurements and Analysis Used for the Determination of the James Webb Space Telescope Integrated Science Instrument Module Vehicle Coordinate System

Abstract

Before the James Webb Space Telescope's Integrated Science Instrument Module could be assembled and tested, it needed a vehicle coordinate system – a frame that everything else would be measured into. This talk gives the mission overview, the goal of the ISIM metrology and the Spatial Analyzer analysis behind it, the data analysis approach taken, and the NASA Goddard analysis that established the frame.
