What direction does 180 degrees correspond to in navigation?

In navigation, the measurement of degrees is commonly based on a compass, where 0 degrees represents North and the angle is measured clockwise around the compass. Therefore, 180 degrees corresponds to the direction directly opposite of North, which is South.

This means that if you were to look at a standard 360-degree compass, turning 180 degrees from North would take you halfway around the circle to South. Understanding this is essential for navigation and flight operations, especially in regards to how directions affect the maneuvers and positioning of an unmanned aircraft.
