SECTION 5 – SYSTEM COMMISSIONING
1. Provisioning of User Services
Within the JetWave™ MCS-8562 Terminal, the Modman LRU is responsible for bringing satellite network
IP access to onboard users through In-flight Entertainment Systems or through Onboard Network Systems.
The Modman LRU coordinates with the 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™ MCS-8562 Terminal.
The commencement of RF transmission and reception of the JetWave™ MCS-8562 Terminal during normal
operation is as follows:
- Satellite Search: The JetWave™ MCS-8562 Terminal is looking for the satellite in the closest longitude
proximity. In this state, the JetWave™ MCS-8562 Terminal does not transmit.
- The Global Signaling Channel is used by the Inmarsat GX network to inform the JetWave™ 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™ system and allows automatic
network configuration and rapid network log-in.
- Data Communication: The JetWave™ MCS-8562 Terminal is logged into the network, and is sending
and receiving data. In the data communication state, the JetWave™ MCS-8562 Terminal may be
switched from one data carrier to another. This can occur for either load balancing reasons, or because
of the JetWave™ MCS-8562 Terminal moved into a different spot beam. During this transition, the
JetWave™ MCS-8562 Terminal continues transmitting normally. At some point, depending on the
aircraft movements, directed satellite handover is used when the JetWave™ MCS-8562 Terminal 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.
Satellite network IP services operate as a managed subscription service model and the services are
provisioned through various service providers. To provision the user services, the Airline Operator need
to associate the JetWave™ MCS-8562 Terminal with any of the service providers and subscribe to the
desired services.
The actual throughputs achieved by the terminal are dependent on the Operator subscription. Each
subscription will have a defined Committed Information Rate which is the minimum throughput guaranteed
to each subscriber. The delivered services will be able to exceed those CIRs where the resources allow
up to defined Maximum Information Rate. All instantaneous demand will be matched to provisioned CIRs
for 95% of the time for every priority level before any remaining bandwidth is allocated to satisfy any
provisioned Maximum Information Rates.
On initial power-up of the system, after uploading the JetWave™ MCS-8562 Terminal configuration files
and entering the aircraft Tail Number, the JetWave™ MCS-8562 Terminal first gets associated to the
Inmarsat network and the system is associated to the appropriate VAR/DP network, where the Service
Level Agreements, the aircraft Tail Number and the pre-assigned JetWave™ system terminal ids are linked
for billing and service.
