Aero-I
Aero I service provides aircraft with simultaneous, two-way digital voice and fax capabilities at speeds equivalent to those offered by the Aero H+ service. Capabilities include digital voice at 4.8 kbps, fax at 2.4 kbps, real-time data at 2.4 kbps and cockpit data at up to 1.2 kbps. Aero I is used for communications in narrow-bodied commercial, business and government aircraft and is International Civil Aviation Organization/Standards and Recommended Practices (ICAO/SARPS) compliant.
Aero I uses smaller, less-expensive satellite communications equipment and antennas. Aero I is designed to meet the regional needs of short- to medium-haul aircraft operators. Aero I voice, fax and data services operate in the Inmarsat spot beams, while packet data transmissions use global beams. Aero I is ICAO/SARPS compliant.

Aero H+ service provides voice at 4.8 kbps, fax at 2.4 kbps and real-time PC modem based data at 2.4 kbps. In addition, Aero H+ offers cockpit data at speeds up to 1.2 kbps and is International Civil Aviation Organization/Standards and Recommended practises(ICAO/SARPS) compliant.
