Global coverage over I-4 satellites

Classic Aero services is used for analog phone, fax and cockpit data communication and operating on Inmarsat I-4 satellites. The Classic Aero service started on airline and business jet usage on I-3 but during summer 2013 the Classic Aero technique was moved onto I-4 satellite system which resulted in two Classic Aero services being depleted; PC-modem data and fax.

Today, if you wish to keep fax functioning a design to upgrade to Swiftbroadband is recommended. In addition, to be future proof then an upgrade is recommended now as cockpit data supporting FANS and CPDLC is scheduled to move from Classic Aero to Swiftbroadband operation in 2014. Therefore, if you wish to have an upgraded satcom network design, please feel free to contact Satcom1 consultancy engineering team.

Current hardware manufactures for Classic Aero are; Cobham, Honeywell and Rockwell Collins.

Classic Services

Aero H
Aero H provides packet data rates of up to 10.5 kbps for ACARS, FANS and ATN communications and up to 9.6 kbps per channel for multi-channel voice, fax and data links through a high gain-antenna – anywhere in the global beams of the I-3 satellites. As well as safety, applications include passenger, operational and administrative communications.

Aero H+
Offers all the features of Aero H, but uses the I-4 regional spot beams and 4.8kbps voice codecs to deliver voice services at lower cost. Outside of regional spot beams, Aero H+ terminals operate in the global beams in the same way as standard Aero H systems. Aero H+ is also available in the full I-4 satellite footprint.

Aero I
Uses intermediate-gain antennas and the I-4 regional beams, providing multi-channel voice and 4.8kbps circuit-switched data services. Aero I packet data is also available in the full I-4 footprint.
