elevation

Elevation is the vertical angle or elevation angle, the inclination at which a satellite is at orbit

with respect to the horizon. The reference plane is the horizontal in the direction of propagation. The elevation angle, denoted by the Greek epsilon, is the angle between the center of the satellite beam and the direction of propagation, usually the earth's surface. Communication with a satellite can only take place from a minimum elevation. The lower the elevation angle, the more the satellite signal is affected by the atmosphere, clouds and rain, and attenuated by absorption and scattering

.

With antennas, the radiation characteristic in the vertical direction is called the elevation diagram, in contrast to the horizontal radiation characteristic, the azimuth diagram.
