1. What is FCC Azimuth?

The FCC (Federal Communications Commission) azimuth calculation determines the compass direction from one point to another in degrees, measured clockwise from true north. It's commonly used in telecommunications for antenna alignment and signal direction.

2. How Does the Calculator Work?

The calculator uses the atan2 function:

Where:

• \( East \) — East component of the vector
• \( North \) — North component of the vector
• \( atan2 \) — Two-argument arctangent function
• \( \pi \) — Mathematical constant pi (~3.14159)

Explanation: The atan2 function calculates the angle between the positive x-axis and the point (North, East), then converts it to degrees.

3. Importance of Azimuth Calculation

Details: Accurate azimuth calculation is crucial for antenna alignment, satellite communication, navigation systems, and any application requiring precise directional information.

4. Using the Calculator

Tips: Enter the east and north components of your vector. The calculator will output the azimuth in degrees (0-360°), where 0° is true north, 90° is east, 180° is south, and 270° is west.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between azimuth and bearing?
A: Azimuth is measured clockwise from north (0-360°), while bearing is often measured in quadrants (e.g., N45°E).

Q2: How do I convert coordinates to east/north components?
A: Subtract the starting point coordinates from the ending point coordinates (easting = Δx, northing = Δy).

Q3: What if my azimuth is negative?
A: The calculator automatically normalizes to 0-360° range. Negative values indicate directions west of north.

Q4: How precise is this calculation?
A: The calculation is mathematically precise, limited only by input precision and floating-point arithmetic.

Q5: Can this be used for magnetic azimuth?
A: This calculates true azimuth. For magnetic azimuth, you'll need to account for magnetic declination.
