Advances in electronics, specifically in the area of digital video processing, have opened the door to many new solutions to old problems. Visually coupled systems using Helmet Mounted Displays have been used for years as an aid to pilot vision. These functions are generally accomplished using a helmet display, head tracker and a mechanically gimbaled sensing system. Although this system has proven to be one effective solution in achieving a wide field of regard with a smaller displayed field of view, it has its limitations and drawbacks. A solid state digital gimbaled system has been developed and flight tested as part of a joint study conducted by McDonnell Douglas and the National Aeronautics and Space Administration. This paper will discuss advantages and limitations of digital gimbal systems.
