OVERAGE
Inmarsat operates strategically placed geostationary satellites called I-3 and I-4. I-3 satellites
provide access to services such as Swift 64 and Aero H/H+, and I-4 satellites provide access to
SBB and Aero H/H+ services.
1. I-3 Satellites
Each I-3 satellite is located over and named after an OR. The four satellite ORs are:
Atlantic Ocean Region-East (AOR-E)
Atlantic Ocean Region-West (AOR-W)
Indian Ocean Region (IOR)
Pacific Ocean Region (POR)
Figure A-1 represents the ORs with approximate transfer
