Can iridium system realize global personal communication?

"Iridium system" is actually a low-orbit global satellite mobile communication network. The satellite "constellation" consists of 66 low-orbit satellites with an operating height of more than 780 kilometers. These 66 small satellites with a diameter of about 1 m are distributed in six elliptical orbits, and each orbit is 1 1. The radio waves emitted by these satellites cover the whole earth. When any phone in the system is started, the nearest satellite and Iridium Network will automatically verify the account number and its location. Then, the user can choose to use cellular communication system or satellite relay system to transmit the information to the destination. Using microwaves, information is relayed between 66 satellites, which shuttle back and forth, much like the relay race of athletes. On the ground, an earth station named "Gateway Station" connects the iridium satellite system with the ground public telephone network, so that any telephone, fax machine, pager and data terminal on the ground can establish communication links with other communication terminals through the iridium satellite system.
