Made by Kelvin Hughes, it projected a 6 feet (1.8 m) diameter image that could optionally be overlaid with a map and range rings. The PDU was originally designed for the ROTOR system and subsequent AMES Type 80-based Master Radar Stations. A smaller version with a 24 inches (610 mm) display was used onboard Royal Navy ships, and a larger version projected onto movie screens was used in the SAGE system in the US.ens was used in the SAGE system in the US.
