Abstract

The Joint Helmet-Mounted Cueing System (JHMCS) incorporates a man-mounted, ejection-compatible helmet-mounted display system, with the capability to cue and verify cueing of high off-axis sensors and weapons, on U.S. Air Force and U.S. Navy single-seat and two-seat fighter aircraft. Program requirements call for the JHMCS to meet a certain level of pointing accuracy. Pointing accuracy is defined as how close the JHMCS computed line of sight (LOS) is to the actual LOS of the pilot. In order to test the pointing accuracy of JHMCS throughout the pilot's range of motion, truth data had to be established sat various azimuths and elevations. Surveyed ground locations do not provide the ability to test at different helmet elevations. Airborne targets do not provide the measurement precision needed to validate system accuracy. Therefore, celestial bodies (stars), whose locations are precisely known for a given time and date at a specific location, will serve as truth data for LOS accuracy testing. This paper addresses the theory, planning, and status of JHMCS accuracy testing utilizing celestial bodies as reference points.
