Transactions of the American Institute of Electrical Engineers, 1933
Equipment that is believed to embody new and interesting features is described in this article. Further refinement in detail and further testing are necessary, however, before the apparatus can be applied to regular service. Its ultimate adoption will depend, of course, upon its ability to compete with other systems of air navigation from the ...

Journal of Navigation, 1974
The use of radio as an aid to navigation is a matter for continual discussion within the Royal Institute of Navigation, and it is the subject of fresh papers in almost every issue of our Journal. Two notable presidential addresses by the second holder of the office, Sir Robert Watson-Watt, in the early 1950s surveyed separately the air and the shipping

Radio-Astronomy and Navigation
The Journal of the Royal Aeronautical Society, 1958The difficulties of determining latitude and longitude under adverse weather conditions, when neither the Sun nor stars can be sighted, are well-known, and the advantages of a non-visual system of position finding which could operate through clouds or fog are too obvious to require emphasis.A Radio Sextant, which detects and locks-on to 8 mm. radiation

Journal of the Institution of Electronic and Radio Engineers, 1986
The initial contribution of radio to navigation was the transmission of time signals and these became established the 1920s. Shipboard direction-finding equipment of the period was cumbersome but efforts to circumvent this drawback gave rise to a long-lasting radio/acoustic technique for determining distance.

Journal of the Franklin Institute, 1928
Abstract The essential engineering features of aircraft radio and associated difficulties are discussed. Solutions to these problems are given although no attempt has been made to describe particular equipment. Two outstanding radio aids to aerial navigation are discussed and a new method described whereby these may be made to operate a visual ...
