Title: Radio navigation system

Abstract: A radio navigation system is disclosed which includes a first pair of fixed transmitting stations, a second pair of fixed transmitting stations and a mobile station. The mobile station includes a receiver having first means for deriving a first signal indicative of the difference in the distances between the mobile station and each of the first pair of fixed stations and second means for deriving a second signal indicative of the difference in the distances between the mobile station and each of the second pair of fixed stations. Summing means are provided for adding the first and second signals to obtain a third signal indicative of a first line of position on which the mobile station is located, and difference means are provided for subtracting one of the first and second signals from the other to obtain a fourth signal indicative of a second line of position on which the mobile station is located.
