WebJul 27, 2015 · v = r ⋅ s r x ⋅ r y. So. v = c o s ( θ) The angle of elevation from r to s is then 90 − a r c c o s ( θ). Is this correct? I'm getting a different result from the accepted answer. The interpretation of r and s are an observer and a satellite orbiting the earth so the desired elevation is the angle above the horizon. coordinate-systems.
