Iridium Certus simplifies satellite communications through a robust, advanced, multi-service platform enabled by the mutli-year upgraded truly global Iridium constellation in early 2019, replacing all its satellites and upgrading the supporting ground infrastructure.

One terminal can now deliver a range of services from multiple high-quality voice lines to the highest throughput L-band data connection available, allowing simultaneous operations for business efficiency.

Offering the highest L-Band data throughput available, Iridium Certus offers the flexibility to scale device speed, size, and power requirements, both up and down, based on the needs of end-users.

Iridium Certus is ideal for high speed requirements on a wide variety of vessels. Iridium Certus delivers optimal benefits of L-Band and Low Earth Orbit in a high-speed solution and under standardized packaging and speeds.

Iridium Certus is also an excellent traditional VSAT companion system. When paired with traditional VSAT, Iridium Certus delivers an ideal hybrid solution combining the benefits of low earth orbit with geostationary orbit and the benefits of L-band with Ku band.

Services include:

  • Background IP Data – Up to 704 kbps
  • Streaming IP Data
  • High Quality Voice (HD)
    • Provides cellular phone type voice quality in mobile satellite network
    • Near toll quality (3.5 MOS)
    • Low latency for real time connection
    • Minimized distortions
  • Prepaid Voice & Data
  • Messaging
  • Safety Services
  • Global Maritime Distress Safety System (GMDSS)

The unique architecture of the Iridium constellation provides inherent advantages in performance and reliability:

  • Everything You Need - With multiple high-quality voice lines, high-speed IP data and safety services in one terminal, Iridium Certus powers all of your communications needs at sea.
  • Best Value - Iridium Certus combines lower cost equipment and better value airtime — without long contracts and high-cost services you simply do not need.
  • Superior Reliability - The Iridium network operates as a fully meshed global canopy with high-speed cross-links designed to deliver uniform coverage and data speed, while Iridium Certus antennas installed on vessels contain no moving parts that might wear out.
  • Absolute Global Coverage - The Iridium network features an overlapping mesh architecture of 66 cross-linked satellites that provides uniform coverage across the globe, including extreme latitudes and throughout the Polar Regions minimizing line-of-sight issues.
  • Low Latency - The Iridium satellites are in Low-Earth Orbit (800 km), so signals travel in 1/40 the time compared to geostationary satellites (36,000 km), resulting in low-latency, high-speed, always-on connections with shorter transmission path and less signal attenuation.
  • Optimal Signal Delivery - Low frequency L-Band signals are resilient to adverse weather and can better penetrate clouds, fog, and rain, while the Iridium network’s Low-Earth Orbit design eliminates equatorial geo-arc interference.

Iridium Certus is already being supported by the certified manufacturers Cobham and Thales, having the corresponding satellite terminals for maritime environments, Sailor 4300 and Thales VesselLINK.

Sailor 4300

Compact and incredibly easy to install, Cobham’s SAILOR 4300 Iridium Connected terminal is a pinnacle of L-band satcom performance and reliability. It ensures that your link to the Iridium network is always available so you can operate safer, smarter, and more efficiently through the power of always available communication and digitally connected applications.

SAILOR 4300 utilizes the Iridium network to provide your on-board link through high bandwidth IP connectivity and three high-quality voice lines for global calling wherever you are.

SAILOR 4300 is designed to withstand the harshest maritime environments. Reliability is high and lifecycle costs are inherently low – it is built to such high quality that there is no scheduled service interval and no maintenance for at least 10 years after installation. In any case, there is also the support and knowledge of Cobham SATCOM’s unique Global Service Network in combination with OTESAT_MARITEL’s one to get you back online wherever you are
