The need in the art is addressed by the improved missile fire control system of the present invention. In the illustrative embodiment, the inventive system is adapted for use with TOW missile systems and includes a telescope cluster assembly () for generating target position signals (). A digital error detector (') receives and processes target position signals () from the telescope cluster assembly (). The processed signals () are then fed to a stabilization control amplifier (), where a microcontroller () steps through a set of instructions eliminate angular noise from the target position signals (). The stabilization control amplifier () subsequently provides feedback to the telescope cluster assembly () for adjusting the line-of-sight in the telescope cluster assembly (). Software instructions for the microcontroller () and constant reference data are stored in the microcontroller memory (not shown). An erasable programmable logic device () is used to output discreet signals for controlling mirror positioning. The inventive set of instructions includes sampling azimuth and elevation error signals (); calculating the average of said azimuth and elevation error signals (); performing a comparison of the average to a specified boresight limit (); performing calculations on the averages in response to information received from the output of the comparison for determining motor runtimes (); and repeating the above steps as necessary for obtaining azimuth and elevation signals within a specified limit.
