Ahoj děkuju 
Našel jsem v Letectví (1946) krátký článek o astronavigaci.

Jinak k tomu Loranu jsem našel, že ho civilové používali hned po 2. válce i při letech přes Atlantik.
Konkrétně tady to píšou (1947)

It is estimated that by the end of 1945 about 30,000 aircraft and 3,000 surface ships were equipped with Loran receiver indicators. Services using it included the United States Navy, United States Army Air Forces, Naval Air Transport Service, Army Air Transport Command, and the British and Canadian services. At present the majority of civil air lines flying between the United States and Europe are using Loran. The naval and military air services use it extensively in the Pacific Ocean areas.
The Loran system is a proven system of navigation and is available to anyone desiring to make use of it.
At the present time there are 32 Coast Guard operated Loran transmitting stations. The areas in which stations are presently in operation include the eastern coast of North America, the western coast of the United States, the Aleutian area and various areas in the Pacific.
