Mace and Matador Guidance Theory
The missile knows where it is at all times. It knows this because it knows where it isn't!
By subtracting where it is from where it isn't, or where it isn't from where it is ( whichever is greater), it obtains a difference or deviation.
The guidance system uses deviations to generate
corrective commands to drive the missile from a position where it wasn't to where it now is.
Consequently, the position where it was is now the position where it isn't.
The "thought process" of the missile is as follows: because a variation has modified some of the information which the missile has obtained, it is not sure where it is. However, it is sure where it isn't! (within reason) and it knows damn sure where it was and also where it wasn't. It now subtracts where it should be from from where it wasn't (or vice versa) and by differentiating this with the algebraic difference between where it shouldn't be and where it was , it is able to obtain the difference between its deviastions and its variations, which is called the ERROR SIGNAL

since I came across it in 1959-60. You may find it appropriate to post somewhere.
