Thrane & Thrane has received Parts Manufacturer Approval (PMA) for its unique Iridium Filter. By eliminating the effects an Inmarsat system may have on an Iridium system installed on the same aircraft, the filter enables the simultaneous use of Inmarsat and Iridium voice/data communication systems. Having been awarded the PMA certification by the Federal Aviation Administration (FAA), Thrane & Thrane's Iridium Filter can now be integrated aboard any aircraft.

Passengers can now benefit from low-cost, multi-channel calls from Iridium as well as high data speeds provided by Thrane & Thrane's Aero-SB Lite Inmarsat system. Until now, system providers haven't found a solution to the complex problems commonly encountered with integrating both systems. With the use of the Thrane & Thrane filter, the Inmarsat and Iridium antennas can be installed within very close proximity, meaning smaller aircraft can take advantage of the system integration. The unique structure of Thrane & Thrane's Aero-SB Lite system makes Thrane & Thrane the only manufacturer that offers this solution, which enables customers to take full advantage of the benefits provided by combining both systems, without impacting the performance of either service.
