2.12 A GEO satellite is located at longitude 343° (17° west), over the Atlantic Ocean. Communication is established through this satellite between two earth stations. One earth station is near Washington, D.C., at latitude 38.9°N, longitude 77.2°W. The other station is near Cape Town South Africa, at latitude 34.0°S, longitude 19.0°E. a. Calculate the look angles for each earth station. Don't forget that the earth station in Africa looks north, and that it has a longi- tude in degrees east. The Washington, D.C. station has a longitude in degrees west and looks south. The numerical values of the earth station longitudes must be added when finding the separation of the stations in longitude. b. Calculate the delay, in milliseconds, for a signal to travel from one earth station to the other via the GEO satellite.
