Abstract

The primary calibration standards for the focal plane structure (FPS) of the Hubble Space Telescope (HST) played a major role in the on-orbit corrections to the telescope during its first servicing mission. Conventional metrology tooling and techniques as well as electronic theodolite metrology system methods were applied to verify the predicted on-orbit positions of the replacement instrument interfaces, latches, and static mechanical envelopes. This paper will discuss the opto-mechanical calibration tooling that was used to develop a high fidelity mechanical simulator of the Aft Shroud region of the HST, and review the processes that were used at NASA Goddard Space Flight Center to verify that the replacement scientific instruments would fit into the flight FPS.
