Abstract : The patent describes a system for accurately and remotely positioning and displaying the position in azimuth of a movable instrumentation package. The package is mounted on a carriage that is driven by an electric drive motor around a circular track. A light beam directed towards two photo cells is broken by a notched metal strip as the carriage moves along the track. The pulses generated by the photo cells are counted with the counter being reset at every ten degree sector to cancel any small accumulated azimuth error.
