How accurate are the bearing and distance results?

The calculator uses the Haversine formula with the WGS84 geodetic system, providing accuracy to approximately 1 meter for typical navigation purposes.

Can I calculate a destination point from a starting location and bearing?

Yes, the tool includes a Destination Point tab where users input an initial bearing and desired distance to compute the resulting coordinates.

Is the tool usable without creating an account or paying a fee?

The Bearing Calculator is 100% free and operates client-side in the browser, requiring no signup or payment to access all features.

What units of distance are provided for the great-circle measurement?

Results are provided in kilometers, miles, and nautical miles, allowing users to select the unit most relevant to their navigation context.

About this tool

What Bearing Calculator does

The Orbit2x Bearing Calculator determines the initial bearing, final bearing, and great-circle distance between any two GPS coordinates. It also supports destination point calculations by inputting an initial bearing and distance. Results are delivered instantly using the Haversine formula with WGS84 precision, and are available in kilometers, miles, and nautical miles. The tool is designed for practical navigation across aviation, marine, hiking, and surveying contexts. Privacy is prioritized as all calculations occur client-side within the browser, and the service is listed as 100% free. A midpoint finder and quick location shortcuts for major cities are also included. A linked guide explains bearing concepts and formula details for users who want deeper context.
