That means that when the U-Boat was turning during the torpedo launch, the longitudinal axis of the torpedo (together with the locked gyro) was turned by the angle tv∗φt, where φt was the angular speed of the turn, which depended on the U-Boat speed and main rudder deflection.

The TvhRe/S3 was connected to the gyro compass.
The rotational speed was calculated automatically, but could also be entered manually.
The SH3 TDC is a simplification.
For example:
The spread angle is entered as the target width in meters (100-200). In SH3, enter the angle directly.
For Fat and Lut torpedoes there were no adjustments at the TvhRe/S3. These were done directly on the torpedo or on an auxiliary board in the bow space.
