HIGH-ACCURACY FREQUENCY STANDARDS IN AERIAL NAVIGATION.
Abstract
A study program was undertaken to determine the desirability and utility of the application of precise clocks (or frequency standards) to aircraft positioning measuring systems (or navigation systems). The study included an investigation of both atomic and crystal frequency standards with regard to their performance relative to this application. It also included the study of long-range navigation systems and their airborne equipment. Systems studied were Loran C and various VLF systems, mainly OMEGA. Some effort also was put into a VHF terminal navigation concept that could be considered a longrange ILS or sectored TACAN. The concept of improved displays and of a simple analog computer for use with a rho-rho precise clocked Loran C system was also studied. A full system design utilizing the equipment studied under this program was not prepared, although detailed block diagrams of all important subsystem components are presented. The general subject studied proved to expand in scope greater than was initially contemplated. (Author)
