HIIII! Da missiwe knuws whewe it is at aww times. It knuws this because it knuws whewe it isn't. By subtwacting whewe it is fwom whewe it isn't, ow whewe it isn't fwom whewe it is (whichevew is gweatew), it obtains a diffewence, ow deviation. Da guidance subsystem uses deviations to genewate cowwective commands to dwive da missiwe fwom a position whewe it is to a position whewe it isn't, and awwiving at a position whewe it wasn't, it nuw is. Consequentwy, da position whewe it is, is nuw da position that it wasn't, and it fowwows that da position that it was, is nuw da position that it isn't.
In da event that da position that it is in is nut da position that it wasn't, da system haz acquiwed a vawiation, da vawiation being da diffewence between whewe da missiwe is, and whewe it wasn't. If vawiation is considewed to be a significant factow, it too may be cowwected by da GEA. Howevew, da missiwe must awso knuw whewe it was. :O

Shout out to the taxpayers, splash ♥♥♥♥♥

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 subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was.
