Loran shore stations always work in pairs: the "master" and the "slave" (see diagram). Both operate on the same frequency and both broadcast the same radio "pulse signals"-short bursts of radio energy transmitted at regular intervals. The pulse from the master station appears as a "pip" on the "scope" of the plane's loran receiver. It also sets off a second pulse from the slave station, which is received as a second pip. The pulses arrive at slightly different times, since they have traveled different distances...
...time lag, which the receiver does automatically in micro-seconds (millionths of a second). For each time lag, a special chart shows a "line of position." The plane's navigator knows at once that he is somewhere on this line. Then he tunes in a second pair of master-and-slave stations operating on a different frequency, and gets a second line of position. His location on the chart is the point where the two lines intersect. A skilled operator can complete the whole problem in less than six minutes...

By telephone the news was spread; the guarantee became a cinch...
