| A. | 3 |
| B. | 2 |
| C. | 4 |
| D. | 1 |
| Answer» B. 2 | |
|
Explanation: 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. |
