A gyro stabilized gun mount is simply connected to the ship's gyros. It's
all low frequency large amplitude signals but has to track position (Type I
control system). Binoculars could be image stabilized (lower in cost) or
gyro stabilized. That control loop (gyro) has higher frequency signals but
can tolerate positional error (Type II control system). The gun mount ships
gyro is a mechanical system. The good optical systems use laser ring gyros.
Aircraft mounted laser pointing systems are the hardest to stabilise. I
serious doubt there are any gyro stabilized shoulder fired rifles. If the
shooter is that shakey he's no marksmen. In the case of the pirates, so what
if the rifle on the ship is stabilized if the target is bouncing all about?
Stabilizing the rifle relative to the earth (absolute space in reality)
doesn't buy anything in accuracy if the target isn't in that reference
plane. It's like bench rest shooting at moving targets. Does anyone remember
the old binocular driven gun directors from before WWII ships and how they
worked?
