Frequently Asked Questions
It calculates the distance to the horizon based on your height above sea level, and the hidden height of an object at a given distance due to Earth's curvature.
Using the formula: distance (km) = 3.57 * sqrt(height in meters). This approximates the distance to the horizon assuming standard atmospheric refraction.
Hidden height is the portion of a distant object that is obscured by the curvature of the Earth. It depends on the observer's height, the object's height, and the distance.
