Classic Aero - Classic over Inmarsat-4 Satellites
Inmarsat-4 Satellites I4 Satellite Capability: 60x more powerful than I3 12 times greater efficiency in its use of radio spectrum 16 times the capacity 25 times the receiver sensitivity. 2 (I4F1 & I4F2) launched in 2005, I4F3 launch this year (~August 08) Satellites will support both SwiftBroadband and Classic Aero services 3G System, much like Cell phone networks 193 Spot Beams per satellite (plus spares) Dynamically Activated / Reallocated Automatic handover
Classic Aero over SATCOM Inmarsat's Classic range of aeronautical services : Aero H: Multi-channel voice, 10.5kbps fax and data, delivered via a high-gain antenna within the satellites' global beams. ICAO approved for safety services. Aero H+: Multi-channel voice, 10.5kbps fax and data, delivered via a high-gain antenna within the spot beams of the Inmarsat-3 satellites and the full footprint of the Inmarsat-4 Atlantic Ocean Region (AOR) satellite, at a lower cost per connection. ICAO approved for safety services. Aero I: Multi-channel voice, 4.8kbps circuit-mode data and fax, delivered via an intermediate-gain antenna. Also supports low-speed packet data. Available in the spot beams of the Inmarsat-3 satellites and the full footprint of the Inmarsat-4 AOR satellite. ICAO approved for safety services. Aero L: Global data communications at 600 to 1200bps, principally to support air traffic control and airline operations. Supports Acars/Aircom messaging. ICAO approved for safety services. Mini M Aero: Single-channel voice, fax or 2400bps data, for general aviation and smaller corporate aircraft. Supports STU-III encrypted voice. Aero C: Supports two-way 600bps store-and-forward data messaging, polling and integrated GPS position-reporting for non-safety-related purposes. Inmarsat's Classic services are delivered within the spot beams of the I3 satellites and the whole footprint of the I4 footprint in the AOR (I4F2) Fuel-saving routing: Oceanic ATC via Inmarsat. In-flight re-routing in response to changing winds can save 15 minutes or more, increasing fuel economies. It is now well-established on major routes over oceanic and wilderness regions. In the North Atlantic, the speed and flexibility of controller / pilot datalink communications mean clearances for flight-level and speed changes are more quickly available, again yielding valuable savings.

Three New Ocean Regions for Classic Aero Requirement for a single aircraft antenna to access multiple services. Inmarsat plans to make Classic available on the I4s ( 7+1 operations; 7 Inmarsat, 1 MTSAT) Inmarsat consulted with the Aero community and determined the appropriate service mix on the I3s and I4s as: Putting Classic on the I4s Allows a single antenna on an aircraft to access SBB & Classic Provides improved redundancy for Classic services Underlines Inmarsat s long term commitment to aero safety service I3 I4 Classic Swift64 SBB
I4 GES Program Status Inmarsat will own and operate GES from BGAN SAS sites post April 09: Hawaii Dual Ocean Region (to view 98W & 143.5E satellites) Fucino (to view 25E satellite) SED is contracted to develop, install and support the Classic Aero GES Squarepeg Communications Inc (SPCI) is SED s principal subcontractor GES will include the FANS improvements as recommended by FANS Satcom Improvement Team Platform is sustainable for many years providing a flexible architecture for expansion
