Iridium satellite communication systems are a global network of low earth orbit (LEO) satellites that provide voice, data, and messaging services to users around the world. The Iridium network consists of three main components: the satellite constellation, the ground segment, and the subscriber terminals.

The satellite constellation is composed of 66 active satellites and several in-orbit spares, distributed in six orbital planes with an inclination of 86.4 degrees. Each satellite is cross-linked to four others, forming a mesh network that enables reliable and low-latency communication anywhere on the planet. The satellites use L-band frequencies, which are more resilient to weather interference than higher frequencies used by geostationary satellites.

The ground segment consists of four primary gateways located in Arizona, Alaska, Hawaii, and Norway, as well as several secondary gateways and network operations centers around the world. The gateways connect the satellite network to the public switched telephone network (PSTN) and the internet, allowing users to communicate with terrestrial phones and devices.

The subscriber terminals are devices that allow users to access the Iridium network. They include satellite phones, personal communicators, messengers, trackers, broadband terminals, midband terminals, external antennas, docking stations, and apps. The terminals can vary in size and functionality.
