Abstract:

The development of pseudo-terrain with statistics which are similar to actual terrain and its application to the analysis of the range-limited horizon comparison system for airborne vehicle position determination is presented. Pseudo-terrain was used to aid in characterizing system performance as a function of terrain roughness. Additional system analyses presented include analyses of system performance effects of changing the horizon range limit or the sensed horizon spacing. Also shown are results of an analysis of system performance for higher vehicle altitudes up to 10Km. A brief analysis of the position accuracy improvement which can be achieved by using along-track and cross-track interpolation of the horizon comparison function is shown. Author
