Guidance system of a missile

Missile guidance, wherein the predetermined path set into the control system of a missile can be followed by a device in the missile which reacts to some property of the earth such as magnetic or gravitational effects, is known as terrestrial reference guidance... 

Guidance Systems. (See also previous item Guided System of a Missile). There are several types of guidance systems (1) They carry, in the missile, devices which enable... 

A modified version of this semiactive technique has the transmitter located in the missile and the receiver of the reflected energy at some remote point. Computation of the desired flight path takes place at a remote point and suitable commands are sent to the missile. This system is known as a quasi-active homing guidance system... 

Thirdly, if new molecules could be synthesized which were to maximize properties and energy, such molecules could be useful even if costly. Much effort has been expended toward synthesizing new compounds for use as liquid propellants. Since that area of the propellant industry is the subject of two other chapters in this volume, I will avoid any detailed discussion of this area. However, in many tactical weapons systems, propellants can be used whose costs would normally be considered prohibitive for a propulsion application. This results from the fact that the rest of the missile propulsion, guidance, and warhead systems are so expensive and the amount of propellant so small that propellants costs become unimportant. The larger the missile becomes, and the more propellant it contains, the greater becomes the consideration of propellant cost. However, the fact that propellant cost may not be crucial has justified much research to prepare new propellants. In fact, several new propellant or propellant ingredients have been synthesized and will find their way into propulsion systems.
