40. The minimum number of geostationary satellites needed for uninterrupted global coverage is : A.3 B.2 C.4 D.1
Option A Solution: In theory, 2 satellites in diametrically opposite geosynchronous orbits could cover the planet. In order for the satellites to communicate, a minimum of 3 would be needed, each at a 60 degree angle to the others. At this point, the strength and quality of coverage increases proportionally to the number of satellites.
