How do you calculate bearing od?

To calculate bearing od (origin-destination) in navigation, you first determine the coordinates (latitude and longitude) of both the origin and destination points. Then, you use the formula for calculating the bearing, which involves the arctangent function to find the angle between the two points based on their differences in latitude and longitude. The formula is typically: ( \text{Bearing} = \arctan\left(\frac{\Delta \text{Longitude}}{\Delta \text{Latitude}}\right) ). Finally, adjust the angle to ensure it falls within the 0° to 360° range, accounting for the quadrant of the resulting angle.
