Iridium is the world's only truly global mobile communications company, with coverage of the entire Earth, including oceans, airways and Polar Regions. Iridium voice and data products provide communications solutions that allow global companies, government agencies and individuals to stay connected, everywhere with the latest models of iridium satellite phones. The unique Iridium constellation of 66 Low Earth Orbiting (LEO) cross-linked satellites routes communications traffic through space and around the world, creating highly efficient and reliable connections. Iridium's constellation consists of 66 cross-linked operational satellites, plus seven in-orbit spares. The satellites operate in near-circular low-Earth orbits (LEO) about 780 km (483 miles) above the Earth's surface. There are 11 satellites in each of six orbital planes and their orbits "intersect" roughly over the north and south poles. The low-flying satellites travel at approximately 17,000 miles per hour, completing an orbit of the Earth in about 100 minutes
Iridium delivers essential communications services to and from remote areas where terrestrial communications are not available. Iridium is constantly finding new ways to expand the possible, including NEXT, next second generation constellation of 66 LEO satellites with enhanced capabilities. In February 2007, Iridium announced a bold vision called "Iridium NEXT." NEXT will replace the company's current satellite constellation with an even more powerful system before Iridium's high quality of service is ever compromised due to constellation age.
Iridium's voice and data telecommunications services are delivered via Iridium satellite phones 9505A and 9555 satellite phones, built to provide reliable service in difficult environments.
Actually the iridium satellite phones in service are:
The Iridium 9555 is still every bit as rugged as its predecessors and tough enough to withstand the world's harshest environments. The Iridium 9555 is 30% smaller and 27% lighter than the Iridium 9505A, plus it still connects to the only truly global mobile communications network. The new Iridium 9555 satellite phone is the smallest phone Iridium has made so far. An internally stowed antenna makes the 9555 less bulky than the 9505A model. While it is sleek, the 9555 retains the ruggedness of the 9505A with excellent water, shock and dust resistance. The 9555 also incorporates an integrated speakerphone, improved texting and email capabilities, a Mini-USB data port and a redesigned and intuitive user interface.
The Iridium 9505A is a compact, light-weight, and extremely durable satellite phone, ideal solution for communicating by voice or data in remote locations and under any type of rugged condition. The Iridium 9505A satellite phone delivers essential communications services to and from remote areas where no other form of communication is available. The 9505A is the world's rugged handheld satellite phone. It offers voice, data and SMS text messaging.
