Impact of Inmarsat satellite repositioning.
Frequently Asked Questions.
Q. Why is Inmarsat planning to reposition the Inmarsat-4 satellites?
A. Inmarsat is repositioning the I-4 satellites in order to optimize the network and -- beginning 24 February 2009 -- to deliver a global service. The repositioning of the satellites will avoid any gaps in coverage and also enhance the quality of service to end-users.
Inmarsat is also required to position two of the I-4 satellites with sight of its new Satellite Access Station (SAS) in Hawaii, which is necessary in order to comply with U.S. regulatory requirements and to avoid interference with other satellite systems operating across mainland North America.

Q. How will Inmarsat end-users benefit from the repositioning?
A. This will provide global coverage for Inmarsat’s broadband services - BGAN, FleetBroadband and SwiftBroadband.

Q. When will repositioning of the I-4 satellites begin?
A. The repositioning of the I-4 satellites begins when the new I-4 Americas satellite enters commercial service over North and South America at 98 degrees West from 09:00 UTC on 7 January 2009. Shortly afterwards, Inmarsat will begin to move the I-4 F2 satellite at 53 degrees West to a new location at 25 degrees East. When this satellite re-enters service on 6 February 2009, Inmarsat will begin the final move, repositioning the I-4 F1 satellite at 64 degrees East, to re-enter service at its new in-orbit location at 143.5 degrees East on 24 February 2009.

Q. What will be the impact on users of the new I-4 satellite covering North and South America?
A. BGAN users will benefit immediately from enhanced quality of service offered by the I-4 Americas satellite, which is positioned more directly over the continents. Also, for the first time, network coverage will be extended to include parts of Western Canada and Alaska.

Q. What action must end-users take to receive service from the new I-4 Americas satellite?
A. There will be a short outage lasting for about one hour, starting from 08:00 UTC on 7 January 2009, for BGAN, FleetBroadband and SwiftBroadband users while the traffic is transferred from the Inmarsat-4 F2 satellite at 53 degrees West to the new I-4 Americas satellite at 98 degrees West. Approximately an hour later, at 09:00 UTC, BGAN users in the region will need to re-point their terminals at the I-4 Americas satellite located at 98 degrees West to pick up the new signal.
FleetBroadband and SwiftBroadband users will not need to take action as their antennas will locate and track the new satellite automatically.BGAN users can download a new version of BGAN LaunchPad provided by Inmarsat to help with the pointing of terminals.

Q. Will there be any disruption to services caused by repositioning the other two I-4 satellites?
A. Broadband services delivered via the Inmarsat-4 (I-4) F1 and F2 satellites, including BGAN, FleetBroadband, and SwiftBroadband, will undergo two separate service outages. The first outage will take place in the Eastern Atlantic, Iceland, Ireland and parts of West Africa, the UK and Greenland; and the second outage in parts of the Asia-Pacific region. Satellite phone services delivered via the I-4 satellites, including IsatPhone, LandPhone and FleetPhone, will undergo a single service outage in parts of the Asia-Pacific region Inmarsat-3 spot beam services in the Atlantic Ocean Region West (AOR-W) - namely Fleet, Mini M, Swift 64,Aero I and Aero Mini M - will undergo a small but ongoing reduction in the geographic area covered by the spot beams.

Q. Why are outages necessary for services offered via the Inmarsat-4 (I-4) satellites?
A. Inmarsat will be moving two I-4 satellites, one at a time. For safety reasons each I-4 satellite must be switched off prior to repositioning. This will leave a temporary gap in coverage in a limited geographical area until the satellite recommences service in its new in-orbit location. As a result, there will be two separate outages in different parts of the world while they move each satellite.

Q. Will maritime and aeronautical safety services be affected?
A. No, maritime or aeronautical safety service will be not be affected by the repositioning, apart from a 30-minute outage while these services are transferred to an Inmarsat-3 satellite in the Atlantic Ocean RegionWest (AOR-W) on 7 January 2009.

Outage period

Service Areas

BGAN 7 January: Iceland, Ireland and parts of West Africa, the UK and Greenland. -

2 February 2009 FleetBroadband/SwiftBroadband: Atlantic strip

Q. What will the impact be on BGAN users after repositioning?
A. BGAN users will need to re-point their antennas at the new satellite in-orbit locations.
BGAN users can download a new version of BGAN LaunchPad provided by Inmarsat to help with the
pointing of terminals. Download BGAN LaunchPad: www.inmarsat.com/Support/BGAN/LaunchPad.

Q. What will be the impact on FleetBroadBand, SwiftBroadBand, and vehicular BGAN users after
repositioning?
A. None. FleetBroadBand, SwiftBroadBand, and vehicular BGAN antennas track the satellite
automatically. No re-pointing is necessary.
Q. Will there be a new version of LaunchPad?
A. Yes. There are already new versions of BGAN LaunchPad and FleetBroadBand LaunchPad showing the
change in coverage. These can be downloaded from Inmarsat’s website.

Q. Will the repositioned I-4 satellites cover the existing Inmarsat Ocean Regions?
A. No. Repositioning will create three new satellite regions, called:
• I-4 Americas
• I-4 EMEA - Europe, Middle East and Africa
• I-4 Asia-Pacific
Q. Where will the I-4 satellites be located after re-positioning?
A. The I-4 satellites will be located as follows:
• I-4 Americas at 98W
• I-4 EMEA at 25E
• I-4 Asia-Pacific at 143E
