The Seeburg plotting table (German: Seeburg-Tisch) was a mechanical plotting table used by Nazi Germany in their operation rooms to track aircraft and coordinate operations during World War II.
The radar position of both enemy bombers and the friendly night fighters were displayed on the table as moving spots of light.
The table had a grid that corresponded to the Kammhuber Line system (or Himmelbett as it was known in Germany) over the sector that was covered by its radar.
[2] The grid was a series of control sectors, that had associated radars, searchlights, and a night fighter.
This smaller grid represented an airspace of roughly 9 x 11 km, a size that allowed the night fighter to find the bombers with its own Lichtenstein airborne intercept radar.
