To receive a signal from one of the DirecTV satellites you need to aim your home dish to line up with the angle and orientation of the satellite orbiting the earth. The orbiting satellite is in a geosynchronous orbit, which means that it orbits at a speed identical to the rotation of the earth so remains in the same relative position when viewed from the ground. Azimuth is the term used to describe the rotation of the receiver dish, and elevation is the term used to describe the tilt. An azimuth is defined by the compass, so a setting of 180 degrees azimuth would be due south on the compass. Tips Writer Bio
