The Gee System in Britain | The Gee System in Britain | ||
At the time that loran was being designed, there existed in Britain a similar navigation system being developed called Gee. Gee was also a pulse-modulated hyperbolic navigation system, similar to loran. Gee operated at ultra-high frequencies and was limited to line-of-sight distances, of 400 miles or so. Gee was intended for aircrafts traveling short distances; not long sea voyages. In mid-1942, R. J. Dippy, who had invented the Gee system, came to the United States for eight months to assist in loran development. Pierce admits that Dippy's basic concept was borrowed by American scientists working on long-range navigation but not Gee designs and nor techniques. He acknowledges that "Loran copied gee's concepts rather than techniques and may be said to have been invented in America in the sense in which Galileo is said to have invented the telescope". | At the time that loran was being designed, there existed in Britain a similar navigation system being developed called Gee.

" The crews of loran stations varied somewhat in size, depending on their locations. They have averaged about fifteen men. As the stations had to be entirely self-sufficient, they had cooks, hospital corpsmen, in addition to the electronic technicians who operated and maintained the transmitters. Each station was commanded by a commissioned officer, usually a lieutenant, with a chief petty officer as second in command. Prospective commanding officers were given a short training course in loran and administration before assignment. Many young men dreaded loran duty because of the isolation, but after it is over, nearly all of them felt it had been well worthwhile. At isolated stations, tours of duty were for one year. The great majority of loran stations were supplied with fuel, bulky spare parts, and large staple items by a Coast Guard supply ship, which called once or twice a year. Unless they were located near a large community, loran stations received mail; personnel, fresh stores, and emergency spare parts by Coast Guard airplane. Most stations had their own airstrip."
