In military aviation, head tracker technologies have become increasingly important to track the pilots head position and orientation, allowing the user to quickly interact with the operational environment. This technology allows the pilot to quickly acquire items of interest and see Fighter Data Link type information. Acquiring the target on a helmet-mounted trackerdisplay which can automatically slew a weapons seeker is far more efficient than having to point at the target with the nose of the aircraft as previously required for the heads-up display type of target acquisition. The United States Air Force has used and evaluated a variety of helmet-mounted trackers for incorporation into their high performance aircrafts. The Dynamic Tracker Test Fixture DTTF was designed by the Helmet-Mounted Sensory Technology laboratory to accurately measure rotation in one plane both static and dynamic conditions for the purpose of evaluating the accuracy of head trackers, including magnetic, inertial, and optical trackers. This paper describes the design, construction, capabilities, limitations, and performance of the DTTF.
