Satcom filter integrates communication systems
Thrane & Thrane introduced an Iridium satcom system filter to eliminate the effects an Inmarsat satcom system might have on an Iridium system installed

Thrane & Thrane introduced an Iridium satcom system filter to eliminate the effects an Inmarsat satcom system might have on an Iridium system installed in the same aircraft. It will enable the simultaneous use of Inmarsat and Iridium voice/data communication systems.

By combining both systems onboard the same aircraft, passengers can benefit from low-cost, multichannel calls using Iridium as well as high-data speed provided by Inmarsat SwiftBroadband systems such as Aero-SB Lite and Aero-SB+.
Until now, system providers haven’t found a solution to the complex problems commonly encountered with integrating both systems. A transmitting Inmarsat system is capable of disabling an Iridium system, which could result in detrimental effects on customers’ voice calls.
