As the world’s leader in 100% worldwide satellite coverage, the products functioning on the Iridium Certus network give users the functionality they require without compromising speed or reliability.

What is Iridium Certus?

Iridium Certus is a multi-faceted satellite communication platform that offers the highest throughput L-band data connection available. This specialty broadband service is powered by the Iridium NEXT constellation. With its 66 low-earth-orbiting satellites, Iridium Certus brings those requiring unlimited worldwide communication the first ever truly global broadband service. 

This type of direct satellite access gives anyone in a fixed remote location or on the move where cellular connectivity is not an option the peace of mind that there will never be an interruption to staying in contact whether that’s for day-to-day business or pleasure interactions or in the event of an emergency


Iridium Certus Low Latency

Iridium LEO Low-Earth-Orbiting satellites have considerably less latency than Geo-Stationary satellites because they are less than 500 miles above the earth and not 23,000 miles away. The network latency of Iridium is predicted to be between 40 and 50 milliseconds. When compared to geostationary satellites, which have a latency of 500 to 1000 milliseconds.
