Question

The angle between the line from the earth station’s antenna to the satellite and the line between the earth station’s antenna and the earth’s horizon is called as ___________

(a) Angle of inclination

(b) Angle of elevation

(c) Apogee angle

(d) LOS angle

I got this question in an interview for job.

My question is from Satellite Orbits topic in section Satellite Communication of Avionics

Answer 1

The correct choice is (b) Angle of elevation

Best explanation: The angle of elevation of a satellite is the angle that appears between the line from the earth station’s antenna to the satellite and the line between the earth station’s antenna and the earth’s horizon. If the angle of elevation is too small, the signals between the earth station and the satellite have to pass through much more of the earth’s atmosphere. Because of the very low powers used and the high absorption of the earth’s atmosphere.
