Fleet 33/55/77

For more than 35 years, Inmarsat has been operating the most reliable mobile satellite communications network and evolving our product and service portfolio to meet our customer's needs.

As new and innovative technologies emerge and marketplace requirements change, our products and services eventually reach their natural end of life (EOL).

Over the past few years, Inmarsat has been communicating the expected EOL dates for the Fleet services. We can now confirm the schedule is as follows:

Service EOL Date
MPDS 31 December 2017
Fleet 33 & 55 31 December 2018*
Fleet 77 1 December 2020

*Fleet 33 & 55 EOL date subject to further validation and may be scheduled earlier in 2018.

What is EOL?

'End of Life - EOL' is the time when the terminals associated with the retired services are deactivated on the network and the services are no longer available to customers.

Note : Please be advised that activations of the Fleet services should cease at least three months prior to the respective EOL dates (as above).

Why is Inmarsat ending Fleet services?

Inmarsat has retired several of our legacy services operating over our Inmarsat-3 (I-3) satellites during the last few years. The I-3 satellites are reaching the end of their lifespan and therefore it is necessary for us to continue the end of life process of our legacy services, including Fleet services.

Note : Inmarsat is committed to providing safety at sea and will continue to offer and support our Inmarsat-C service. This service will be migrated to the Inmarsat-4 (I-4) satellites.

What service migration options are available?

Fleet F33 brings facilities and services previously available only on much larger vessels directly to users on smaller vessels in the Inmarsat spot beams. Fleet F33 delivers digital voice calling, fax and dial-up data service at 9.6 kbps. Plus, with available V40/V42 compression, Fleet F33 can provide apparent data speeds of up to 40 kbps.

Fleet F33 Mobile Packet Data Service (MPDS) provides "always connected" benefits combined with data-based billing. This always-on, higher-speed option is particularly suited to IP-based data applications, such as Internet, intranet access and e-mail.

If you require a higher bandwidth option, consider Fleet or FleetBroadband from Stratos.

Fleet F55 offers you the versatility to choose from spot beam services such as Mobile Packet Data (MPDS), ISDN, PSTN and global low cost voice telephony; providing a communications solution with global reach. The F55 is designed for use in the medium yacht market and commercial trading markets, other than deep sea.

In essence, Stratos Fleet F77 is a marine-enabled Inmarsat GAN. It is an integrated service that allows you to choose from Mobile Packet Data (MPDS), ISDN, PSTN and low cost voice telephony.

Mobile Packet Data provides an "always on" channel where you only pay for data sent and received, not the time connected. In effect, "your thinking time is free". Fleet 77 offers cost effective Internet Access, as well as real-time telemetry, SCADA and messaging applications.

Fleet F77 from Stratos also provides dedicated 64Kbps ISDN connectivity, enabling high-speed data transfer and high quality voice, fax and video, a 3.1 kHz audio channel for the connection of analogue devices as well as low cost "mini M" voice telephony and fax. Stratos offers enhanced Fleet F77 128Kbps service on a global basis.
