   ich glaube, es ist mal wieder Zeit für folgenden (schon älteren) kleinen

   Funktionsweise der Navigationselektronik ...   
      
      
   The equipment, and hence the aircraft, knows where it is all times. It   
   knows this because it knows where it isn't. By subtracting where it is   
   from where it isn't (or where is isn't from where it is, depending which   
   is greater), it obtains a difference or deviation. The internal guidance   
   system uses deviations to generate corrective commands to fly the   
   aircraft from a position where it is to a position where it isn't. The   
   aircraft arrives at the position where it wasn't, thus, the position   
   where it was is now the position where it isn't. In the event that the   
   position where it is now, is not the same as the position where it   
   originally wasn't, the system will acquire a variation (variations are   
   caused by external factors and discussion of these factors is beyond the   
   scope of this simple explanation). The variation is the difference   
   between where the aircraft is and where the aircraft wasn't. If the   
   variation is considered to be a significant factor, it too may be   
   corrected by the internal guidance system. The aircraft must now know   
   where it was. The 'Thought Process' of the equipment is as follows:   
   because a variation has modified some of the navigation information   
   which the aircraft acquired, it is not sure where it is. However, it is   
   sure where it isn't and it knows where it was. It now subtracts where it   
   should be from where it wasn't (or vice-versa) and by differentiating   
   this from the algebraic difference between where it shouldn't be and   
   where it was, it is able to obtain the difference, (called error),   
   between its deviation and its variation ...

   alles klar?
