2.8 For a variety of reasons, typical minimum elevation angles used by earth sta- tions operating in the commercial Fixed Services Satellite (FSS) communications bands are as follows: C-Band 5°; Ku-Band 10°; Ka-Band 20°. a. Determine the maximum and minimum range in kilometers from an earth station to a geostationary satellite in each of the three frequency bands. b. What is the round-trip signal propagation times for each of the ranges? You may assume the signal propagates with the velocity of light in a vacuum even when in the earth's lower atmosphere.

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
