An Iridium satphone, sat phone is a type of mobile phone that connects directly to satellites in space instead of cell towers on land. They provide similar but limited functionality to smartphones we have in our pockets. Primarily satphones used for voice, text messaging or SMS, and low-speed data connection, but don’t confuse it with internet browsing on an iPhone. Portable handheld satphones and pocket-sized iridium GO cannot provide reliable internet connection for everyday internet browsing.
The Iridium satellite constellation provides voice and data coverage to satellite phones, pagers and integrated transceivers over the entire Earth surface. Apart from other satellite systems, Iridium satellites are not geostationary which means they do not stay in the same spot but move relative to the ground eliminating dead reception zones.
The advantages of Iridium satphones include but not limited to wireless coverage with no gaps, Integrated SOS button for 911 Emergency calls. GEOS Support – International Emergency Response Coordination Center, known worldwide for emergency response coordination. One other feature which stands out amongst other phones is Integrated GPS receiver. It allows the subscriber to optionally add Location Based Tracking (LBS) service which could be used for various applications.
