All satellites are tracked using two main indicators called 'azimuth' and 'elevation'. These two measurements have been used since the first days when man started writing down the positions of the stars and planets as observed from the earth.
AZIMUTH
Azimuth is a 360° measurement of a point along the horizon of the earth. This measurement starts at zero at the point on the compass that indicates north, and counts up clockwise with East being 90°, South 180°, and West 270°.
ELEVATION
The angle to the satellite from the observer's position as measured from the horizon is referred to as the 'elevation'.
Using just these two measurements, we can point the satellited dish at a satellite and start receiving a signal.
