Performance
Scientific paper
The Goddard High Resolution Spectrography, (GHRS), has been in operation since the launch of the Hubble Space Telescope in April 1989. While this instrument has proven it's value to the scientific community, a number of operational and hardware problems had to be addressed to enable it's continued use. This paper will detail the symptoms, analysis and resolution of each of these problems. Issues to be covered include the effect of spherical aberration on the target acquisition software routines, performance of the optical element carrousel motor and electronics, and the impact of a failure in the side one low voltage power supply.
