What percentage of the earth can communication satellites see?(a) 20(b

1.	What percentage of the earth can communication satellites see?(a) 20(b) 50(c) 70(d) 40The question was asked by my college professor while I was bunking the class.I need to ask this question from Satellite Orbits in section Satellite Communication of Avionics
Answer» Right option is (d) 40 To elaborate: Most COMMUNICATION satellites in USE today are of the geosynchronous variety. Approximately 40 percent of the earth’s SURFACE can be “seen” or accessed from such a satellite. Users INSIDE that area can use the satellite for communication.
