The interlace loop (Figure 2-16) is a position servo loop.
position of the gimbal is determined and positioned by the scan
The reference signal is developed by the
The gimbal position signal is
amplified and compared with the reference signal by the driver and
comparator circuit which generates an error signal. The error signal
is used to operate solenoid No. l and is balanced with the signal
from the differentiator to operate solenoid No. 2.
