1. What Is Reverse Bearing Calculation?

Reverse bearing calculation determines the opposite direction of a given bearing. In navigation and surveying, it's used to find the direction exactly 180 degrees from the original bearing.

2. How Does The Calculator Work?

The calculator uses the reverse bearing formula:

Where:

• \( bearing \) — Original bearing in degrees (0-360)
• \( RB \) — Reverse bearing in degrees (0-360)

Explanation: The formula adds 180 degrees to the original bearing and applies modulo 360 to ensure the result stays within the 0-360 degree range.

3. Importance Of Reverse Bearing Calculation

Details: Reverse bearing calculation is essential in navigation, surveying, and various engineering applications where determining the opposite direction is required for return paths or symmetrical measurements.

4. Using The Calculator

Tips: Enter the bearing in degrees (0-360). The calculator will compute the reverse bearing, ensuring the result remains within the valid degree range.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of valid bearing values?
A: Bearings should be between 0 and 360 degrees, inclusive.

Q2: How is modulo operation applied in this calculation?
A: The modulo operation ensures that when (bearing + 180) exceeds 360, it wraps around to the beginning of the degree circle (e.g., 400 mod 360 = 40).

Q3: Can this calculator handle decimal values?
A: Yes, the calculator accepts decimal values for more precise calculations.

Q4: What are some practical applications of reverse bearing?
A: Navigation return routes, surveying back-sight measurements, and determining opposite directions in various engineering applications.

Q5: How accurate is the calculation?
A: The calculation is mathematically precise, with results rounded to one decimal place for readability.
