GPA-30 Long Range Search Radar Video Mapper Set - A Long-Range Search Radar Video Mapper set built by ????. This mapper produces a video map outline of the radar set coverage area that is synchronized with the radar video sweep and rotation and displays this map outline on up to 12 plan position indicators (PPI) associated with the search radar. The GPA-30 generates the video map from an opaque film negative of the territory surrounding the radar site. The maps used are circular with the radar site at the center; the range of the map corresponds to the max range of the search radar displays. The map video is mixed with the video signals from acquired targets, permitting the operators to locate the position of a radar target with respect to a point on the earth's surface.
