SUMMARY OF VALUABLE FEATURES OF THE LORAN SYSTEM The features which make Loran a valuable tool and a highly regarded sup- plement to the art of navigation are inherent in the technology of the system itself. It is a radio device which makes use of the speed of travel of radio signals as its fundamental principle. This quality is known scientifically to be the most stable and unchanging electrical characteristic of radio waves and consequently the Loran system stems from a firm and proven scientific foundation. The outstanding features of the Loran system may be summarized as follows: (1) Loran fixes may be obtained readily at long distances from the trans-
