Abstract
Space Dynamics Laboratory performed various combinations of pointing mirror calibration of one of their vacuum and liquid nitrogen (LN2) rated ground support equipment (GSE) calibrators incorporating a pointing mirror gimbal. For this calibration approach, a theodolite was utilized to measure object space beam angles as a function of pointing mirror gimbal setting. This paper discusses the test setup, calibration uncertainty, angular coverage, measurement combinations, and explores the magnitude of dependencies.
