Abstract:
(This paper describes a pioneering telecommunication satellite system( Iridium based on a global digital satellite, which aims to provide portable telecommunication services through small common units, capable of using terrestrial mobile systems and digital communica- tions. This operator has global quality and offers phone calls anywhere in the world. The result explains that based on the findings of this article and the statements of its researchers, this communication satellite system is the pioneer of personal communication based on global digital satellite. Its main mission is to provide portable telecommunication services through small shared units capable of using terrestrial cellular systems. It should be noted that these common units use low-power phones with low antennas. Calls are sent and re- ceived using L-band frequencies in an Fdma/Tdma universal access system. In addition, paging, fax and data services are also available through the Iridium constellation. Intersat- ellite links provide "switching in the sky" and transmit .voice calls to Earth
