Bearing and Navigation Calculator
Calculate bearing, distance, and coordinates for navigation and surveying
About this calculator
The Bearing and Navigation Calculator is an essential tool for surveyors, navigators, pilots, and outdoor enthusiasts who need precise directional measurements and coordinate calculations. This calculator determines the bearing (compass direction) between two points, calculates distances using great circle formulas, and converts between different coordinate systems. Whether you're planning a hiking route, conducting land surveys, or navigating maritime or aviation routes, this tool provides accurate calculations for safe and efficient navigation across any terrain or waterway.
How to use
Enter your starting coordinates (latitude and longitude) and destination coordinates into the input fields. Select your preferred units (degrees, radians, or compass bearings) and distance measurements (miles, kilometers, or nautical miles). Click calculate to get the bearing direction, total distance, and intermediate waypoint coordinates for your navigation route.
Frequently asked questions
What's the difference between true bearing and magnetic bearing?
True bearing uses geographic north as reference, while magnetic bearing uses magnetic north. The difference is called magnetic declination, which varies by location.
How accurate are the distance calculations?
The calculator uses great circle distance formulas on the WGS84 ellipsoid, providing accuracy within a few meters for most navigation purposes.
Can I use this for marine navigation?
Yes, the calculator supports nautical miles and provides bearings suitable for marine navigation, including coastal and offshore route planning.
