SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
The Aspire-200 can access services from two of Inmarsat's satellite networks. The I-3 satellite network
provides Swift 64 services, and the I-4 satellite network provides SwiftBroadband (SBB) services.
Throughout 2018, Inmarsat will transition Swift64 services to the I-4 network and then decommission
the I-3 network.
3. About Inmarsat Services
A Swift 64 connection provides 64K Speech voice, low cost AMBE voice, ISDN 64K data, and MPDS (Mobile
Packet Data Service). Only one service is available at a time. ASPIRE can provide one 64kbps channel
when using an HGA. You can use ISDN or MPDS to access the Internet or other ground-based networks,
or high-quality voice services to access terrestrial phone networks.
The applications available with a Swift 64 connection include:
•
Telephony: in-seat, mobile, VoIP and text messaging
•
Email, intranet, internet and instant messaging
•
Secure VPN access
•
Large file transfer
•
In-flight news updates.
An SBB connection provides simultaneous data and voice services. In Standard IP mode, data service is
shared among other users on the Inmarsat spot beam. In Streaming IP mode, users receive a guaranteed
rate of service—8, 16, 32, 64, 128kbps, or XStream, which can be combined to create higher rate
connections.
An SBB connection can serve similar applications as the Swift 64 connection, but with more simultaneous
users and optional guaranteed rates of transfer. In SBB mode, you can specify various rates of service to
different users and applications, for example, a low-rate service for an email user and a higher rate service
for a user transferring large files.
4. SwiftBroadband Service Classes
Inmarsat classifies SBB satellite communication services according to the capability of the system. The three
classes of systems are:
•
SBB Class 15—can provide data services including background IP up to 200kbps, up to two streaming
IPs of 8kbps or 16kbps, a single streaming IP (8kbps to 32kbps) and one Ambe+2 low cost voice.
•
SBB Class 7—can provide data services including background IP up to 330kbps, multiple streaming IPs
(8kbps to 128kbps), 56k RDI, 64k UDI, 3.1KHz (fax) and one Ambe+2 low cost voice.

Aspire-200
•
Class 15 systems can only access SBB services when the angle to the satellite
is greater than 20 degrees.
•
An Aspire-200 equipped with an Omni antenna can access only Class 15
services.
•
Class 7 systems can access packet-switched services when the angle to the
satellite is greater than 10 degrees.
