Azimuth: The angle between a celestial body (satellite) and the North, measured clockwise around the observer’s horizon is called azimuth.
(For example, if the celestial body (satellite) due North has an azimuth of 0º, one due East 90º, one due South 180º and one due West 270º.)
Elevation: The angular distance between a celestial body (satellite) and the observer’s local horizon or the observer’s local plane vertically is called elevation.
Where, A = Azimuth of antenna in degree
E = Elevation of antenna in degree
S = Satellite longitude in degree
N = [ithoughts_tooltip_glossary-glossary]Site longitude [/ithoughts_tooltip_glossary-glossary] in degree
L = Site latitude in degree
G = S-N
Dhaka location longitude 90024’ latitude 23051’ satellite orbit location 105.50. So, what is the A & E?
Solution: Longitude, N = 90024’ = 90.690
Latitude, L = 23051’ = 23.50
Satellite orbit location, S = 105.50
G = S –N
= (105.50 – 90.690)
A = 1800 tan-1[tan(14.91)/sin(23.5)]
