The Genesis of the Decca Navigator System

The Decca Navigator System was very unusual among radio-navigation systems in that the entire system was championed and marketed by a commercial company. How it came about was also unusual -it was neither the product of market research nor a military specification. It was a solution to one of the major problems of the 1930s facing those who attempted to use radio methods for the location of vehicles, that of measuring extremely small time intervals. The problem was eventually solved by pulse methods (radar), which were kept very secret at the time, but Decca offered an alternative particularly suited to marine navigation because of its use of low frequencies. No matter how good a technical solution, many systems fail if they are not actively supported by proper marketing and in this Decca Navigator was fortunate to have the backing of a major British company, the Decca Record Company. This paper describes the inception, wartime trials and eventual acceptance into general marine use of Decca Navigator. Some previously unpublished historical material from the company archives is included.

“…Probably the first use of this hyperbolic principle was not by radio at all but by using the sound waves generated by guns firing in WW1 bombardments. Microphones were located at known points and the time-of-arrival of the sound of the guns firing was used to find their position (Powell, 1981).…”

Loran‐C is a radionavigation system that has been operational since 1958. The initial development was started during World War II and since that time the system has evolved through several stages. The number of applications and the extent of the system have also significantly increased. In this paper, a historical perspective of Loran‐C is presented starting from its inception during WWII. An extensive list of references is provided at the end of the paper for those who desire a greater historical perspective.
