SwiftBroadband Avionics

All major avionics suppliers are developing SwiftBroadband avionics• Extension to ARINC 741 and 761 systems• Smaller lighter ARINC 781 systems

A choice of SwiftBroadband equipment • All will have Aero safety services• Weight/power for a two-channel installation (Including antenna and classic aero

services) 110 lbs / 200 watts• ARINC 781 single box SB avionics

Major Manufacturers include:• EMS• Honeywell• Rockwell Collins• Thales• Chelton

Network Infrastructure - Information Assurance

SwiftBroadband uses enhanced 3G security protocols defined by 3GPP (www.3gpp.org)

SwiftBroadband uses:• Kasumi algorithm for ciphering over the satellite link• Integrity protection for signaling between the User Terminal and the Radio

Access Network (RAN)• Private key mutual authentication• SIM card/PIN number physical authentication

Satellite control protected by NSA Type 1 Caribou encryption

Network• Firewalls installed in the SAS/border gateways• Link encryption may be applied across the DCN

End-to-end encryption can be applied at the application layer transparent to the services

What Inmarsat brings to UAS/UAVs

• Reliable service• Real time, toll quality voice for remote pilots• Worldwide connectivity• Proven, trusted partner for DOD and NATO allies• Relevant, flexible form factor for terminals• Transition path to higher capacity

Meeting requirements for highly reliable backup communications; real time voice

communications and where range exceeds existing comms coverage

Next Generation MSS: Global Xpress

Inmarsat recently announced plans for fifth generation constellation to augment 4th generation L-band BGAN network• I-5 is a strategic move into the Ka-band for next-generation Mobile

Satellite Services (MSS)• Boeing will build the satellites and partner in commercialization

Key features of the new Global Xpress network include: • Seamless, global coverage & end-to-end ground network • Augments and compliments Inmarsat’s BGAN services• System capacity and bandwidth step-changes for end users

º >25 Gbps = exponential improvement in system capacity º ~ 50 Mbps in forward direction and ~5 Mbps in return direction to 60cm
