What is a fix?

What is a fix?

• A. Provides a more precise location
• B. Uses two lines of bearing to triangulate
• C. The distance to the transmitter
• D. A time stamp for the signal

Answer: (A)

In navigation, a fix is the determination of your exact position on a chart. It’s the point you can tell yourself you’re at with sufficient accuracy, not just a single measurement like distance or a timestamp. So the option that says a fix provides a more precise location best captures what a fix is—the result you obtain after processing signals to pinpoint where you are. The other ideas describe parts of the process or measurements that can contribute to locating you: knowing how far you are from a transmitter is a range, a timestamp is timing information, and using two lines of bearing is one method (triangulation) to figure out a position. But none of those alone define what a fix is; they’re components or methods that help you arrive at the precise location.
