Abstract
An overview of the results from measuring the shape, performance, and alignment of a 2-m composite High Gain Antenna (HGA) is presented. Many measurement techniques were used in conjunction to verify the utility of the HGA for use on the New Horizons mission to Pluto. Vector metrology between optical references provided a measure of internal alignment between components. Close-range digital photogrammetry was used during thermal vacuum testing (to -170 C) to verify shape and component alignment at temperature. And coherent laser radar measurements provided a dense matrix of dimensional measurements, supporting photogrammetry results and allowing analytical verification of measured RF performance.
