Abstract : The system expected to provide navigation capability for all-weather low altitude flight has been identified in simplified block form. Two components, the navigation information processor and the computer processor have been determined as requiring the major portion of this research effort. Three methods of attack for solving the problems have been employed. First, state-of-the-art has been ascertained together with a critical analysis of claims made by contemporary designs. Second, special consideration has been given to modifying present systems in order that they more nearly fill the requirements imposed by the low-level flight regime, and third, consideration has been given to ideas generated within and without of this organization for future development and implementation. Answers to the problems of geometries, definitions, and requirements of information transfer displays have been obtained. Tentative agreement on development of timing techniques to provide for accurate range-range measurements has been reached as the method to implement for low altitude navigation. (Author)
