Thank you for the Nicolaus day surprise.
Which I still don't understand this is the stabilization of the mirror when the gun is locked in the loading angle. Which component measures the deviation of the LOS/mirror from the zero position (vertical and horizontal)? In other stabilization systems a gyro is always used.
Which way does take this signal , which specific assemblies are involved in this way of the signal? And how is the correction done on the mirror in the end? The mirror can be swiveled vertically. That has been clarified. But can the mirror also be rotated horizontally? Or is an additional prism twisted inside? Or is the aiming mark shifted horizontally?
The gyro block is a special Yugoslav development. Is it so that this gyroblock can also output a signal when the gun is locked in the loading angle? It is sufficient to measure the angular velocity.
I had read Dragan Petković's dissertation on this. Unfortunately, the description of the stabilization is very sketchy.
From there is this block diagram that I edited a bit.
