How is a position plotted using LORAN-C?

• A. By Triangulation With Three Towers
• B. By Measuring Depths
• C. By Satellite Signals
• D. By Comparing Line Figures To LORAN Curves On The Chart

Answer: (D)

LORAN-C plots your position by converting the measured time difference between signals from the master and a secondary station into a line of position on the chart. That time difference corresponds to a specific hyperbolic curve, which are the LORAN curves printed on the chart. By plotting the observed line figure and matching it to these curves, you determine where you are along that line. Using a second master station provides another line of position, and your location is found at the intersection of the two lines. This approach relies on comparing lines of position to the chart’s LORAN curves, not on triangulation with towers, depth measurements, or satellite navigation.
