End of life for Inmarsat Aero-M & Inmarsat Aero I
Date Published: 2016-04-12 Date Modified: 2019-04-22

End of life for Inmarsat Aero-M & Inmarsat Aero I & the upgrade path.

Aero M: As of September 30, 2014, new applications for the INMARSAT Aero Mini M service are no longer accepted and the service will no longer be provided as of December 31, 2016.

Aero I: Aero-I service is supported at least until the end of 2018.

The upgrade path for Aero I and Aero M is with an Inmarsat SwiftBroadband Intermediate Gain system.

The good news is that most aircraft (with an Aero I or M system) have an antenna already installed and certified that is compatible with the new SwiftBroadband service – this saves a lot of money on hardware, labor and certification costs. Upgrading to SwiftBroadband increases the value of the aircraft and it will provide world-wide internet and voice except over the extreme N and S poles. Being able to advertise an aircraft that has world-wide internet, not just over the continental US, makes this feature attractive to passengers. If the aircraft is sold, world-wide capability will interest buyers all over the world which will increase value and/or possibly result in the aircraft selling quicker than others.

If your aircraft is equipped with a Cobham or Thrane and Thrane Intermediate Gain Antenna IGA-5006 part number 405006A it is compatible with SwiftBroadband service. The upgrade path is to change the SDU PN 403068A with the Cobham 405040A SBU and the High Power Amplifier / Low Noise Amplifier (HPA/LNA) part number 403010K with HLD part number 405016A. There will be some wiring changes or other changes depending on the original installation. 

AirSatOne offers top-tier support and competitive airtime, in fact we are the only service provider not afraid to publish our prices on-line. See our SwiftBroadband Price Guide for operating costs.
