The Advanced Visual Target Acquisition System AVTAS has been developed by the Naval Weapons Center to enable the Agile weapon system to rapidly acquire an airborne target at large off-boresight angles. The pilots task is to simply establish a good sight picture of a target and line up on that target an optical sight which is rigidly attached to the pilots helmet. The AVTAS, which is a helmet tracker, ultimately computes the digital direction cosines in aircraft coordination of the pilots line of sight. These direction cosines are used to drive the Agile seeker system to rapid target acquisition. AVTAS is an electro-optical system that uses no moving parts, is lightweight, does not restrict the pilots movement or vision, has a wide field of view, and can be flown in high performance fighter aircraft. AVTAS has been designed for use in both laboratory and flight test programs to evaluate the operational characteristics of the system. Author
