IRT-NX SATCOM system for Iridium®

Our SATCOM solution to support the new Iridium Certus network

Data expectations in aircraft are constantly changing, from the amount of data transferred to new data applications — all requiring the need for more data bandwidth. We not only see this in our daily lives, but also while traveling and in aircraft operations. Today’s aircraft operators are looking for reliable, safe data interaction, in addition to the flexibility to grow with future SATCOM needs. That’s why Collins Aerospace became a Value Added Manufacturer for the new Iridium Certus satellite network. 

Collins Aerospace can help you meet your SATCOM requirements with high data rate capability and lower weight, drag and power usage than with other SATCOM offerings. The Certus network will bring increased data speeds. Through our ARINC GLOBALink℠ and ARINCDirect℠ offerings, Collins Aerospace is a service provider for Iridium’s Certus satellite solutions for commercial airlines and business aircraft operators. We can help meet your service needs by taking advantage of Certus’ higher data speeds at lower data costs.

With over 3,000 legacy Iridium systems fielded already, we’re adding Iridium Certus services to our comprehensive suite of aircraft connectivity applications for commercial, government and business customers. Data rates are currently up to 352 kbps with future planned upgrades to 704 kbps and, when available from Iridium, up to 1.4 Mbps.
