They are used for mobile applications such as COMMUNICATION to ships, vehicles, planes, hand-held terminals and for TV and radio broadcasting. 2 They are responsible for providing these services to an assigned region (area) on the earth .
3 The distance r = (g·R2/(2·π·f)2)1/3 From the above equation it can be concluded that the distance of a satellite to the earth‟s surface depends on its rotation frequency.
