SYSTEM COMMISSIONING
6.1 Provisioning of User Services
Within the JetWave
TM
system, the Modman LRU is responsible for bringing Inmarsat satellite
network IP access to onboard users through In-flight Entertainment Systems or through Onboard
Network Systems. The Modman LRU coordinates with the Inmarsat Satellite Access Station (SAS)
for modulation, demodulation, power control, terminal authentication, configuration, IP
communication, QoS aspects and initiating tracking and beam switching for the JetWave
TM
system.
The commencement of RF transmission and reception of the JetWave
TM
system during normal
operation is as follows:
Satellite Search: The JetWave
TM
system is looking for the satellite in the closest
longitude proximity. In this state, the JetWave
TM
system does not transmit.
The Global Signaling Channel is used by the Inmarsat GX network to inform the
JetWa
ve
TM
system terminal of the current satellite configurations and location. Inmarsat
satellite generates a global beam which illuminates the entire service region in the
satellite’s footprint. Global Signaling Channel makes the frequencies and locations of
each spot beam known to the JetWave
TM
system and allows automatic network
configuration and rapid network log-in.
Data Communication: The JetWave
TM
system is logged into the network, and is sending
and receiving data. In the data communication state, the JetWave
TM
system may be
switched from one data carrier to another. This can occur for either load balancing
reasons, or because of the JetWave
TM
system moved into a different spot beam. During
this transition, the JetWave
TM
system continues transmitting normally. At some point,
depending on the aircraft movements, directed satellite handover is used when the
JetWave
TM
system needs to switch between the satellites. The antenna re-pointing is
required. The frequency band of the transmissions shifts and the KANDU will track on the
new carrier. During this satellite transition, there will be a momentary disruption to the IP
data connectivity.
Inmarsat GX Aviation services operate as a managed subscription service model and the services
are provisioned through various Value Added Resellers/Distribution partners. To provision the user
services, the Airline Operator need to associate the JetWave
TM
system with any of the Value Added
Resellers or Distribution Partners and subscribe to the desired Service Subscription Package
services. The following is the current list of Value Added Resellers for AT&R market and Distribution
Partners for BGA market:
