Abstract

The need for the helmet-mounted display (HMD) to present flight, navigation, and weapon information in the pilot's line-of-sight has continued to rise as helicopter missions increase in complexity. To obtain spatial correlation of the direction of the head line-of-sight and pilotage imagery generated from helicopter-mounted sensors, it is necessary to slave the sensors to the head motion. To accomplish this task, a head-tracking system (HTS) must be incorporated into the HMD. There are a variety of techniques that could be applied for locating the position and attitude of a helmet-mounted display. Regardless of the technology, an HTS must provide defined measurements of accuracy. System parameters include motion box size, angular range, pointing angle accuracy, pointing angle resolution, update rate, and slew rate. This paper focuses on a hybrid tracker implementation in which a combination of optical and inertial tracking using strap-down gyros is preferred. Specifically, this tracker implementation is being examined for the high-accuracy attack rotorcraft market which requires a high degree of accuracy. The performance and resultant cost of the tracker components are determined by the specific needs of the intended application. The paper will also indicate how the various requirements drive the cost, configuration, and performance of the resultant hybrid head-tracker.
