So yeah, the periscope is connected to the ships gyrocompass, which gets speed from the underwater log. |
Well, you are right, the speed is used to get the corrected course. But all the gyro repeaters (driven by gyro compass) receives only course. At the end of the periscope manual you have wiring of the plug and socket. You can see there two power lines (R1 and R2)and three phase lines (S1, S2, S3).
Here you have got wiring of the repeaters:

There is no way to transmit speed, only the course.
