Iridium®: The possibilities are endless

Powered by a uniquely sophisticated global constellation of 66 cross-linked Low-Earth Orbit (LEO) satellites, the Iridium® network provides high-quality voice and data connections over the planet’s entire surface, including across oceans, airways and polar regions. The flexible software-based design of the Iridium® network serves as the technological backbone for the development of an impressive array of industry defining products and services. The unparalleled coverage and high dependability of the Iridium® network mean that Intellian’s customers can rely on critical communication lifelines when and where needed most.

Strategic partnership

The most technically advanced Iridium® Certus maritime terminal

The Iridium® constellation provides inherent advantages in performance and reliability over other mobile satellite services providers:

  • The large number of fast-moving satellites with multiple overlapping spot beams minimizes missed connections and dropped calls.
  • The cross-linked satellite architecture permits Iridium® to operate with increased reliability.
  • The low-Earth orbit provides a shorter transmission path with less signal attenuation.
  • L-band frequency is unaffected by weather conditions.

Iridium®: True global coverage

Iridium’s unique constellation architecture makes it the only network that covers 100% of the planet. Satellites are cross-linked to provide reliable, low-latency, weather-resilient connections that enable communication anywhere in the world. The Iridium® constellation is in Low-Earth Orbit (LEO), approximately 780 kilometres (485 miles above the Earth, providing stronger signals and faster connectivity through smaller antennas with lower power requirements. Additionally, the unique structure of Iridium's Low-Earth Orbit allows satellites to converge at the poles, ensuring coverage in the remote high-latitude regions where no other satellite provider has coverage. Iridium's LEO network uses L-band frequencies to communicate with the users. These frequencies are more resilient to weather, providing reliable communications even in adverse conditions in the air, on the sea, or on the ground. 

True Global Coverage

  • Iridium® LEO network of 66 satellites
  • Pole to Pole coverage
  • Low-Earth Orbit, stronger signals
  • Low latency, high speed and always-on
  • GMDSS Ready*

Intellian Certus® Terminals

The C700 can deliver out-of-the-box uplink speeds of 352Kbps and downlink speeds of 704Kbps, with equally impressive low-elevation-angle RF efficiency thanks to its unique 12-patch phased array antenna design. It will support three high-quality, low-latency phone lines simultaneously. The C700 winterized version is the first terminal that is certified by Iridium® with an operational temperature range -50°C ~ +55°C (-58°F ~ 122°F).
The Intellian C200 Maritime terminal is the latest product developed at Intellian’s new L-Band Center of Excellence in London, UK.

Powerful performance

Iridium's network is designed with multiple redundancy levels, ensuring that communication is always available, even if one or more satellites fail. Iridium's network together with Intellian Certus terminals can support a wide range of applications, including voice, data, and messaging services, and it can be used by a variety of industries.
