The Iridium System
The Iridium System is a satellite-based, wireless personal communications network providing a robust suite of voice and data features across the planet.
The system is comprised of three principal components: the satellite network, the ground network and the Iridium subscriber products including phones and data modems.
The design of the Iridium network allows voice and data to be routed virtually anywhere in the world. Voice and data calls are relayed from one satellite to another until they reach the satellite above the Iridium Subscriber Unit (handset) and the signal is relayed back to Earth.
The satellites are in a near-polar orbit at an altitude of 485 miles (780 km).
They circle the earth once every 100 minutes traveling at a rate of 16,832 miles per hour.
Each satellite is cross-linked to four other satellites; two satellites in the same orbital plane and two in an adjacent plane.
The ground network is comprised of the System Control Segment and telephony gateways used to connect into the terrestrial telephone system.
The System Control Segment is the central management component for the Iridium system. It provides global operational support and control services for the satellite constellation, delivers satellite tracking data to the gateways, and performs the termination control function of messaging services.
The System Control Segment consists of three main components: four Telemetry Tracking and Control sites, the Operational Support Network, and the Satellite Network Operation Center. The primary linkage between the System Control Segment, the satellites, and the gateways is via K-Band feeder links and cross-links throughout the satellite constellation. Gateways are the terrestrial infrastructure that provides telephony services, messaging, and support to the network operations.
The key features of gateways are their support and management of mobile subscribers and the interconnection of the Iridium network to the terrestrial phone system. Gateways also provide network management functions for their own network elements and links.
The healthy satellite constellation is demonstrating outstanding longevity. |
