Iridium is a global satellite communications company that operates a network of 66 low Earth orbit (LEO) satellites. These satellites provide voice and data communication services to users on the ground, as well as to aircraft and maritime vessels. Iridium's satellites operate in the L-band frequency range, and they are able to provide coverage to virtually every point on the Earth's surface, including the poles and oceanic regions that are not covered by other satellite systems.

The Iridium system offers a variety of services, including voice and data communication, GPS-based location services, and "distress signaling" capabilities that allow users to send emergency messages in the event of an accident or other crisis. Iridium's satellite-based telephone service is particularly useful for users in remote or hard-to-reach areas, such as sailors at sea or hikers in remote wilderness areas. Iridium also offers satellite-based Internet services for businesses and organizations, such as asset tracking and monitoring, weather data, and remote sensor data collection.

Iridium's LEO architecture allows for very low latency (about 1 second) and high-speed data communications (up to 251 kbps) which makes it suitable for some of the most challenging applications like flight tracking, maritime and land-mobile communication, and M2M(machine-to-machine) solutions.

The system is frequently used by governments, militaries, emergency services, and other organizations that need reliable communication in remote or hard-to-reach areas, as well as by individuals such as sailors, pilots, hikers, and other outdoor enthusiasts.
