Iridium
Iridium Satellite Communications
Iridium’s low Earth orbit satellite network delivers truly global voice and data connectivity, from polar regions and open oceans to remote land operations where dependable coverage is critical.
Global satellite network
Connectivity built for places other networks cannot reach
Iridium is one of the most recognised names in satellite communications because its network is designed for genuinely global reach, including oceans, remote land areas, and polar regions. For users operating beyond the limits of terrestrial coverage, that makes Iridium a powerful option for voice, messaging, tracking, IoT, and broadband-style services.
Whether the requirement is a handheld satellite phone, a compact tracker, a field-ready communicator, or a more advanced Certus terminal, Iridium supports users who need dependable communications in environments where resilience matters more than convenience.
Global reach
Pole-to-pole coverage across land, sea, and air-facing operations.
Flexible services
Voice, messaging, tracking, IoT, and Certus connectivity across multiple device types.
Operational reliability
Well suited to maritime, expedition, emergency, industrial, and remote field use.
Why Iridium
A network built for resilience and reach
Iridium stands apart because its satellite architecture is built around continuous global availability rather than regional reach. That makes it especially valuable for users whose work, travel, or operations take them well beyond conventional communications infrastructure.
Truly global coverage
Iridium is widely used where consistent availability matters, including polar regions, open oceans, isolated land routes, and remote industrial environments.
Low Earth orbit performance
The LEO constellation supports responsive communications and helps deliver a more practical user experience for mobile and remote applications.
A broad ecosystem of solutions
From handheld devices and trackers to IoT modules and Certus terminals, Iridium supports a wide range of operational use cases.
Network architecture
Mesh design and responsive connectivity
Iridium’s satellite constellation uses an interlinked architecture that allows the network to support resilient communications across the globe. For end users, that translates into dependable availability and a network that is designed to work far beyond the limits of region-specific systems.
Whether supporting voice calls, short data bursts, tracking, or operational messaging, Iridium is built for users who need a communications platform that remains useful in remote, mobile, and hard-to-reach environments.
Certus and broadband
Iridium Certus for voice, data, and operational connectivity
Iridium Certus is a flexible service platform designed to support a wide range of communications requirements, from smaller-scale data applications through to higher-demand operational connectivity. It is used across maritime, land, and broader remote-sector environments where uptime and dependable access are a priority.
For vessels, command units, remote teams, and mobile operations, Certus can provide a more capable communications layer than handheld-only devices alone, supporting applications that require stronger data performance while still benefiting from Iridium’s global reach.
Coverage
Truly global coverage
Iridium’s satellite constellation is designed to provide coverage across the entire planet, including remote oceans and polar regions where many other services cannot operate in the same way. For users with genuinely global movement or exposure, that coverage is one of Iridium’s strongest advantages.
Iridium coverage is global, reaching the full surface of the Earth, including polar regions and open oceans.
