Reverse Bearing Formula:
| From: | To: |
The reverse bearing calculation determines the opposite direction of a given bearing. It is commonly used in navigation, surveying, and various engineering applications where directional relationships need to be established.
The calculator uses the reverse bearing formula:
Where:
Explanation: The formula adds 180 degrees to the original bearing and applies modulo 360 to ensure the result stays within the valid compass range of 0-360 degrees.
Details: Calculating reverse bearings is essential for navigation, route planning, and determining return paths. It helps establish reciprocal directions and is fundamental in various geospatial applications.
Tips: Enter the bearing in degrees (0-360). The calculator will compute the reverse bearing, which is exactly 180 degrees opposite to the input bearing.
Q1: What is a bearing in navigation?
A: A bearing is the direction or path along which something lies or moves, typically measured in degrees clockwise from north.
Q2: Why do we need to calculate reverse bearings?
A: Reverse bearings are used to determine the opposite direction, which is useful for return journeys, establishing reciprocal relationships, and various surveying applications.
Q3: How does the modulo operation work in this context?
A: The modulo 360 operation ensures that the result remains within the valid compass range of 0-360 degrees, wrapping around when the sum exceeds 360.
Q4: Can this calculation be used for magnetic bearings?
A: Yes, the same formula applies to both true and magnetic bearings, though magnetic declination should be considered for precise navigation.
Q5: What are some practical applications of reverse bearings?
A: Navigation, surveying, construction layout, antenna alignment, and any application requiring reciprocal direction calculations.
