Remarks
Azimuth is measured positive in an easterly direction from the observer's local north in a
plane tangent to the surface of the central body at the location of the observer. Using this
convention, local north is at 0-degrees azimuth, local east is at 90-degrees azimuth, local
south is at 180-degrees azimuth, and local west is at 270-degrees azimuth.
Elevation is the angle between the relative position vector and the plane tangent to the
surface of the central body at the location of the observer and is measured as positive
away from the central body.
