The SHOC instrument uses an Andor iXon camera, an Intelligent Reference TM-4 GPS unit, and a host PC which acts as a controller for the instrument. A filter wheel is usually used in conjunction with these. The host PC and GPS are installed in a crate which is mounted beneath the telescope. The filter wheel and camera are mounted beside this, in the light path. The software describing the various components is described below.
