Loran consist of three components: 1. a chain of radio transmitters in operations 24/7 to create an electronic lattice or grid upon the surface of the earth. 2. a loran receiver-indicator in each ship or aircraft and 3. loran nautical charts or tables published by the US Navy Hydrographic Office. A simple explanation of loran can be found is section on loran as an Attachment named "American Practical Navigator" | Loran consist of three components: 1. a chain of radio transmitters in operations 24/7 to create an electronic lattice or grid upon the surface of the earth. 2. a loran receiver-indicator in each ship or aircraft and 3. loran nautical charts or tables published by the US Navy Hydrographic Office.

By 1 October 1942 a chain of four loran transmitting stations in the US and Nova Scotia were on the air. Loran receivers began to be shipped and installed on selected naval vessels and a group of radio technicians were sent to training schools in Cambridge. | By 1 October 1942 a chain of four loran transmitting stations in the US and Nova Scotia were on the air.

To what extent loran was born out of Gee's concepts is unresolved and academic. Gee was also a pulse-modulated hyperbolic navigation system, similar to loran. Gee operated at lower frequencies and was limited to line-of-sight distances, of 400 miles or so. Gee was intended primarily for aircraft during WW2. | |||
