Iridium Certus: The World’s First Truly Global Broadband Service

Iridium Certus Overview

Iridium Certus® - the advanced new multi-service platform powered by Iridium
Powered by the Iridium NEXT low-Earth orbit satellite constellation, Iridium Certus® is a new multi-service communications platform set to disrupt the industry status quo by bringing a more efficient, reliable and cost-effective way to achieve 100 per cent global connectivity. With uncompromising coverage and speeds reaching up to 1.4 Mbps, even in the most remote areas of the Earth, Iridium Certus will deliver pole to pole enterprise-grade services while redefining the limits of mobile satellite network communications.

Iridium Certus® is being built to support an innovative portfolio of partner products and satisfy a wide-ranging set of aviation, maritime and land mobile communication needs. The multi-service platform will provide users with the voice, data and broadcast options they need to meet the ever-increasing demands of field communications. Whether your application is large or small, high-speed or low-speed, Iridium Certus can be used to deliver the right service for your business needs.

Enterprise Grade
Iridium Certus® will provide peace of mind that your operational needs will always be met. With exceptional availability and fully scalable high-performance solutions, Iridium’s reliable, global network will ensure that your mission- and business-critical capabilities are supported. Iridium’s service offerings will also grow with your business over time. Through an array of best-in-class terminals, Iridium Certus® will accommodate a full range of services – streaming data, high-quality voice, data broadcast and safety services – all built on a single platform. If you expand into new regions, increase your volume of users, or need higher data speeds to support your applications, Iridium Certus will scale with your enterprise to ensure you have the right solution at the right time.

Iridium Certus® is the new multi-service platform powered by the $3 billion Iridium NEXT constellation. With uncompromising coverage and a range of speeds eventually up to 1.4 Mbps, Iridium Certus® will deliver global, pole to pole reliable, enterprise-grade services while redefining the capabilities of mobile satellite network communications.

The unique overlapping architecture of Iridium NEXT will provide availability, redundancy and reach no others can match. Unlike distant geostationary satellite networks that limit the geographic use and are subject to service degradation in inclement weather, Iridium Certus® operates from a network of 66 low earth orbiting satellites that provide service anywhere on the planet, even in poor weather conditions, without compromise.

Iridium® stands alone as the only truly pole-to-pole satellite network. Through a crosslinked and overlapping “mesh” architecture, Iridium’s global coverage means that you are never out of reach, regardless of your location. Using this powerful network as the backbone for service, Iridium Certus® is poised to set the standard for remote communications and connectivity for enterprises, governments and individuals that want to extend their use of mobile networks into remote areas.

Iridium Certus Key Facts

What’s in a name?
The Latin word ‘certus’ translate to ‘certain, reliable, and sure’, which are key attributes of the new service.

How does it work?
Iridium Certus is powered by Iridium NEXT, Iridium’s next-generation, $3 billion satellite constellation. It has been coined the largest ‘tech refresh’ in history, as Iridium replaced 66 low Earth orbit satellites with new ones, all in just about 18 months.

What makes Iridium Certus stand out?
Iridium Certus delivers new options to the satellite broadband market. For example, in the maritime market, Iridium Certus provides a real choice for end-users, ending an industry monopoly that has existed for some time. The service delivers competitively priced, high-performing, pole-to-pole global satellite coverage supporting many important functions including, business operations, IoT applications, crew welfare and critical safety services.

How is Iridium Certus different from the competition?
Iridium Certus is highly reliable, due to the advantages of the network’s unique architecture. Located in low Earth orbit (LEO), with crosslinks enabling cross-satellite communication and L-band end-user transmissions, the network is unaffected by weather conditions or the need for ground stations, unlike other satellite networks, like those located in Geostationary Orbit (GEO).

How is Iridium Certus more than satellite broadband?
The service is designed to be a multi-solution platform for all industry verticals. It provides multiple high definition voice lines, alongside IP data speeds debuting at 352 Kbps and soon after upgraded to 704 Kbps. With speeds reaching approximately 1.4 Mbps, Iridium Certus also delivers multiple streaming classes and safety services.

Who can use Iridium Certus?
Compared to existing L-band services and equipment, Iridium Certus offers superior value. Whether you are a large vessel with heavy data needs, or a smaller operation, our model makes it possible for any industry to have access to reliable, high-quality satellite connectivity, anywhere on the planet.

Which terminals support the new service?
Iridium has partnered with Cobham, the Thales Group, Rockwell Collins, L3 Communications, all world-class, Value Added Manufacturers (VAMs), to develop cutting-edge terminals to support Iridium Certus. For the maritime market Cobham’s SAILOR 4300 and VesseLINK by Thales, are easy to install, light-weight small form factor antennas. Their design and competitive price points bring much-needed value, choice and increased quality of service to the maritime market. Existing Iridium devices such as Iridium Pilot® will continue to function normally but will not benefit from the new Iridium Certus speeds without one of the Iridium Certus terminals.
