What is Position Fixing?

What is Position Fixing?

• A. A method of navigating by measuring position relative to some known object.
• B. A process to fix the time at a known position.
• C. A technique to orient by magnetic north only.
• D. A method to determine altitude by barometric pressure.

Answer: (A)

Position fixing is the process of determining your exact location on the map by using measurements relative to known objects or references. In practice, you observe bearings or distances to objects with known positions (landmarks, signals from fixed beacons, celestial bodies, etc.) and then compute where those observations intersect to pinpoint where you are. This is precisely what the described method does: navigating by measuring position relative to a known object. The other ideas describe time determination, orientation, or altitude estimation, none of which establish your horizontal position on the chart.
