What is Azimuth and Elevation?
Azimuth (sometimes known as ‘Az’) is the angle of rotation from True North. 0° being North and 180° being South. Elevation (sometimes known as ‘El’) is the pointing angle up from the ground or horizon. 0° is the horizontal angle looking along the ground and 90° is the vertical straight up or ‘zenith’ pointing angle. In the northern hemisphere the angles are different to those in the southern hemisphere. This is because below the equator you would look north to the equator and to the satellite but in the northern hemisphere you would look south to the equator. When at or near the equator the angles are more extreme. Elevation angles are almost 90° pointing straight up and the azimuth angle becomes much more significant.
