LORAN-C can pinpoint a boat position within how much of a mile almost anywhere in the world?

LORAN-C can pinpoint a boat position within how much of a mile almost anywhere in the world?

• A. One Mile
• B. One Quarter Mile
• C. One Half Mile
• D. Three Quarters of a Mile

Answer: (B)

LORAN-C works by measuring the differences in arrival time of signals from a master station and one or more secondary stations. Those time differences map out hyperbolic lines of position on a chart, and by taking signals from multiple stations, you pinpoint the boat where those lines intersect. Because the timing and the network are designed for global coverage, this system can locate a vessel to about a quarter of a mile in most parts of the world, under good conditions. The other distances are less precise than what LORAN-C typically provides, which is why the quarter-mile figure is the best choice.
