SYSTEM DESCRIPTION AND INSTALLATION MANUAL
JetWave™ System

traffic can be started once the antenna is pointed correctly to the satellite and the terminal locks on
to the satellite for providing the connectivity. The system enables all the supported services like
continuous BITE, SNMP, Access system, user services, etc. in this mode.
The system enters the Normal Operating Mode approximately 5 minutes after continuous power is
applied to the last LRU.
D. Critical Fault Mode
The system enters into Critical Fault Mode when any LRU reports a critical fault that cannot be
recovered and will affect satellite connectivity. The RF transmission is muted and user services are
disconnected. The system may support minimal services like SNMP, continuous BITE, Access
system, etc. in this mode.
E. Data Load Mode
The system enters Data Load Mode when aircraft is on ground and local data load discrete on the
Modman is asserted. The SNMP, Access System, and continuous BITE services may not be
supported in data load mode. The RF transmission is disabled in data load mode. The Modman
provides ARINC 615A Ethernet data loading to itself and other
LRUs through its own interface in
Data Load Mode. Additionally, LRUs individually provide ARINC 615A data loading via their
configured ports. The APM and the KRFU do not support ARINC 615A data loading individually and
are data loaded via the Modman and the KANDU, respectively. The system can exit to Data Load
Mode when local data load discrete is asserted.
F. Commanded Mode
The system also provides a Commanded Mode of operation which may be initiated through the
SNMP when the aircraft is on ground. This mode provides access to user initiated tests for system
testing e.g. manual antenna alignment, initiating automatic antenna alignment, transmit cable
calibration, manual antenna pointing to defined location, etc.
5. About Inmarsat Services
The JetWave™ system is made up of a fleet of Ka-band broadband satellite network from Inmarsat. The
Inmarsat-5 (I-5) geostationary satellites have high power Ka-band steerable and fixed spot beams that
supply global in-flight connectivity services to business, commercial, and government aviation customers
around the world.
The JetWave™ AES provides Ka-band communication utilizing an airborne VSAT. The AES
communicates through a satellite to an SAS. TX and RX interface provided within the AES enables
two-way communication. The forward channel provides a communication path from the SAS to the AES.
The return channel provides a communication path from the AES to the SAS.
The JetWave™ system may not be available on the ground or in the air in certain geographical areas.
Some countries do not allow access to this service in their airspace. The service availability would also
depend on the country in which the aircraft is registered with. The aircraft operators may approach the
respective Value Added Resellers /Distribution Partners for further details where JetWave™ services are
not available.
