STANDARD LORAN {A Long Range Aid fo Navigational System) INTRODUCTION The Loran system is a modern electronic aid to navigation by means of which navigators on or over the ocean can determine their position accurately and quickly, day or night, and under practically any condition of weather and sea. The name "Loran" was derived from the words "LOng RAnge Naviga- tion," which describe in general terms the system's relative utility when com- pared to ranges of other electronic navigational aids. The effective range of Loran is as great as 1,400 nautical miles at night and 750 miles during the day (fig. 1-1). The accuracy obtained is comparable to that which may normally be expected from good celestial observations. Even though such precision is attained, the determination of position by Loran requires but 2 to 3 minutes' time. The navigator can think of Loran merely as a method of determining.
