Low earth orbiting satellite - leo, английский
Low earth orbit satellites which require 77 small, smart satellites to provide linkage around the world. the satellites move overhead in glossary/51 their low orbit. motorola`s iridium (from the element iridium which has 77 electrons) uses the concept to provide, digital, satellite-based personal communications via small, handheld transportable receivers. with the system, voice, fax, or data calls can be made or received anywhere. the user will have one universal telephone number for the phone. local gateways will store customer billing information, keep track of user locations, and interconnect with terrestrial carriers worldwide. the dual-mode phone will access customers` regular cellular service first, switching to iridium only when there is no terrestrial signal, to assure least-cost routing. the system is planned to be launched in 1994 with service by the end of 1996. inmarsat`s project 21 will provide similar services.
