In addition to the range of individual pairs of stations, the integrated Loran system is so arranged that coverage is available over most of the major shipping lanes of the world.

(2) The accuracy of Loran fixes is of high order. Results comparable to those obtained by means of good celestial observations are consistently effected. (3) Loran operation is nearly independent of the weather. It is not affected by conditions of the sea or air and does not suffer from doubtful effects encountered with older types of radio navigational devices such as direction finders. (4) The time required to obtain a Loran fix is short. Experienced operators seldom require more than 2 to 3 minutes to establish a fix. (5) Operation of Loran shipboard and aircraft equipment is relatively simple and navigators may be trained in Loran technique in a very short Figure 1-6.—Vessel making port on Loran line of position.
