The minimum number of geostationary satellites needed for uninterrupted global coverage is :
-
- 3
- 2
- 4
- 1
- 3
Correct Option: B
In theory, 2 satellites in diametrically opposite geosyn-chronous 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.
