Paper Abstract

The payload portion of James Web Space Telescope (JWST) consists of a deployable, three mirror anistigmat, telescope and an Integrated Science Instrument Model (ISIM) that contains the scientific instruments. This paper describes the overall process and strategy of aligning the Observatory in an efficient manner that reduces risk and strives to be tolerant of faults in the system. A process has been developed consisting of ground calibration of the instruments and alignment testing of the fixed optics to ensure that the telescope is alignable in space. The overall architecture of the alignment process and the processes to safely and efficiently conduct the optical commissioning is described.
