Frequently Asked Questions
Earth's curvature refers to the bending of the Earth's surface, causing objects to disappear over the horizon as distance increases.
Hidden height is approximated by h = d^2 / (2R) * 1000, where d is distance in km and R is Earth's radius (6371 km). Then subtract observer and target heights.
If the result is 'Visible', the line of sight is not blocked by curvature, meaning the target can be seen from the observer's position.
