For example, if you had a satellite dish and wanted to point it at a specific communications satellite, you would need to know the look angle, generally described by the azimuth and elevation angles. Importance of Look Angles have been discussed. The angle of elevation of a satellite is that angle which appears between the line from the earth station antenna to the satellite and the line from the earth station antenna to the earth’s horizon. Just measure one time to figure the correlation of a specific dish's LNB arm angle to the aiming elevation angle. For an azimuth axis, this is the time at which the satellite reaches its maximum elevation angle, and the magnitude of the maximum required shaft speed is essentially independent of the azimuth pointing direction of the satellite's velocity vector.
