cycles will now only be performed at key points in the predicted path to maintain an up to date 
model. 
 
Note that the IntelliTrack tracking algorithm cannot perform correctly with data that has been 
gathered before the sensors have been initialized or with an inaccurate terminal heading. 

 

 

 

Note – Any time a step track failure occurs a spiral scan will be performed in an 
attempt to find the target.  If three successive step track failures occur tracking will 

stop.
