Animated film "A Missile Named Mac" explains basics of missile guidance systems developed by Bell Laboratories.

NEW VERSION with improved video & sound: https://www.youtube.com/watch?v=KFz0x...

Public domain film from the Library of Congress Prelinger Archive, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization.

Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its "Single Shot Kill Probability" (SSKP), which is part of combat survivability calculations associated with salvo combat model.

These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active," "passive" and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion...

Guidance systems are divided into different categories according to what type of target they are designed for - either fixed targets or moving targets. The weapons can be divided into two broad categories, Go-Onto-Target (GOT) and Go-Onto-Location-in-Space (GOLIS) guidance systems. A GOT missile can target either a moving or fixed target, whereas a GOLIS weapon is limited to a stationary or near-stationary target. The trajectory that a missile takes while attacking a moving target is dependent upon the movement of the target. Also, a moving target can be an immediate threat to the sender of the missile. The target needs to be eliminated in a timely fashion in order to preserve the integrity of the sender. In GOLIS systems the problem is simpler because the target is not moving.

GOT systems

In every GOT system there are three subsystems:

- Target tracker
- Missile tracker
- Guidance computer

The way these three subsystems are distributed between the missile and the launcher result in two different categories:

- Remote Control Guidance: The guidance computer is on the launcher. The target tracker is also placed on the launching platform.

- Homing Guidance: The guidance computers are in the missile and in the target tracker...

GOLIS systems

Whatever the GOLIS guidance system, it must contain preset information about the target. These systems' main characteristic is the lack of target tracker. The guidance computer and the missile tracker are located in the missile. There is only one type of guidance system of this kind: Navigational Guidance.

Navigational guidance is any type of guidance executed by a system without target tracker. The other two units are on board the missile. These systems are also known as Self Contained Guidance Systems, however they're not always entirely autonomous due to the missile trackers used...
