🔍 Key Concepts

• LORAN (LOng RAnge Navigation) uses timing differences between signals from a master and one or more slave stations • Each measured time difference between a master and a slave defines a line of position (LOP), not a full fix by itself • A fix is the intersection of at least two independent lines of position on the chart

💭 Think About

• Think about how many different time-difference measurements (master–slave pairs) you need to draw enough lines of position to pinpoint one spot on the chart • Ask yourself: Does one master–slave pair give you a single line of position or an exact point? What do you need to turn that into a fix? • Consider how many slave stations a single master must work with so that the receiver can compute more than one independent time difference

✅ Before You Answer

• Confirm what a line of position (LOP) represents versus a fix • Verify how many independent time-difference readings are needed to get a position fix (think of crossing LOPs) • Check which option provides enough master–slave combinations to yield at least two intersecting LOPs for a fix
