Abstract : This final report contains the results of the analysis of a Rho-Rho Navigation System using a high-accuracy frequency standard in the aircraft, intended for transoceanic flights in the North Altantic area. Only the VLF (Omega) and LF (Loran-C) transmissions are considered prac ticable for this purpose, and the LF (LoranC) system, having definite advantages, is recommended for use. Existing Loran-C stations across the Atlantic provide adequate coverage with sufficient navigational accuracy. After building the planned station in Newfoundland (probably in 1965) the positioning accuracy capability of this system will be even better. The Rho-Rho- Loran-C receiver can be made substantially simpler than the conventional Loran-C receiver. The tie-in of the proposed Rho-Rho Navigation System with the existing aircraft doppler-radar system is explored in this study. (Author)
