Altitude graph on radio channel. Calculation of line of sight based on coordinates and antenna heights. Calculate visibility in the Fresnel zone for a given frequency. The expected receiving signal level is calculated by free space loss, transmitter power and antenna gain.

Distance

Calculation of distance, azimuths between two points. The height of the earth's surface above sea level.

Next point
