Telemetry Room:
Riva Bella Fire Direction Tower
Ouistreham, Normandy
This is a full-scale replica of the Telemetry Room of the Riva Bella Fire Direction Tower. A model of the entire tower is located behind you.
Situated on the Tower's fifth floor, the Telemetry Room housed a stereoscopic range finder similar to the one seen here. The range finder was capable of scanning the horizon to a distance of over 15 miles. An observer looking through the site would initially see two identical images of a target. To determine the target's distance, he would turn the instrument dials until the two images merged to create one picture. The distance was entered into a fire-control calculator to determine firing coordinates. These coordinates were then relayed to the gun crews by telephone. |
