The minimum number of geostationary satellites needed for uninterrupted global coverage is :
A. 3
B. 2
C. 4
D. 1
Answer: Option A
Solution (By Examveda Team)
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.This Question Belongs to General Knowledge >> Physics
