This paper describes a method for evaluating helmet-mounted tracker accuracy installed in an aircraft sitting stationary on the ground. A test measurement test space is established by surveying numerous targets and ground control points with a laser surveying instrument. An aircraft is inserted arbitrarily into this test space and key points on the aircraft are surveyed along with the same ground control points originally surveyed. Mathematically, the two spaces are made to coincide at the ground control points, and then the entire space is transformed to place the aircraft so that the surveyed aircraft key points are located at their manufacture specified position. The helmet operator then looks at each target while other test operators record tracker output data. Data is subsequently analyzed.
