Q. The minimum number of geostationary satellites needed for uninterrupted global coverage is :
Answer: 2
Notes: 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.
