The satellites relevant for the reception of satellite TV and radio programmes are positioned in a geostationary orbit in the so-called "Clarke Belt", which can be found at an altitude of 35.803 km directly above the equator.

The satellites positioned there are in analogous motion with the earth's own rotation, so that they appear to be stationary above a constant point on the earth's surface. This is the basis that allows us to constantly receive satellite signals by means of a fixed, mounted antenna on the earth surface.

Dependant on the satellite's position in this orbit, e.g. ASTRA at 19.2° East, and the position of the satellite antenna relative to the East/West and to the North/South direction, two values can be found which are essential in order to position the antenna correctly for the desired satellite, viz. the "azimuth angle" and the "elevation angle".

Azimuth is the angle relating to the horizontal positioning of the dish. The angle is expressed in terms of degrees, with North = 0 degrees, South = 180 degrees.

Elevation is the angle above the horizon, and is also expressed in terms of degrees. This is the angle by which the dish must be "tilted" in relation to the theoretical horizon, in order to position it precisely for the desired satellite.
