How many Geo-synchronous satellites are required for uninterrupted world broadcasting?
A
3
B
4
C
2
D
1
Correct Answer: 3
In theory, 2 satellites in diametrically opposite geo-synchronous orbits could cover the planet. In order for the satellites to communicate, a minimum of 3 would be needed, each at a 60° angle to the others. At this point, the strength and quality of coverage increases proportionally to the number of satellites.
