A network of 24 plus Earth Stations and four active satellites, providing Global satellite coverage. The satellites are in geo-synchronous orbits (GEO) above the equator, which means they are always in the same place in the sky.

Inmarsat is a 62 member-country, internationally owned cooperative, which operates and maintains the network, satellites and all the earth stations. Inmarsat was formed over 20 years ago in order to facilitate communications to the commercial shipping and fishing industries. This is one reason why the Inmarsat network has major role with the International Maritime Organization, IMO, for required communication aboard certain class and type of boats and ships. The IMO approved Inmarsat systems have built-in Emergency Distress features, that can aid a vessel in distress.

Starting with a user base of 900 ships in the early 1980s, it now supports links for phone, fax and data communications at up to 64kbit/s to more than 210,000 ship, vehicle, aircraft and portable terminals. That number is growing at several thousands a month.

The Inmarsat business strategy is to pursue a range of new opportunities at the convergence of information technology, telecoms and mobility while continuing to serve traditional maritime, aeronautical, land-mobile and remote-area markets.

Keystone of the strategy is the new Inmarsat I-4 satellite system, which from 2004 will support the Inmarsat Broadband Global Area Network (B-GAN) - mobile data communications at up to 432kbit/s for Internet access, mobile multimedia and many other advanced applications.

Inmarsat's Broadband Global Area Network – BGAN – is the world's first mobile communications service of any kind to provide both voice and broadband data simultaneously through a single, truly portable device on a global basis. It is also the first mobile communications service to offer guaranteed data rates on demand.

RBGAN (Regional Bgan) AN INMARSAT NETWORK

RBGAN COVERAGE MAP

Launched at the end of 2002, Regional BGAN offers high-speed access to the Internet, as well as intranets and other private networks. Coverage stretches across almost all of Africa and Asia, including Indonesia and the western half of Australia.

The maximum bandwidth within each spot-beam is 144kbit/s. But because Regional BGAN is a packet data network, the average bandwidth available is shared among several connected users if they transmit data at the same time.

The Regional BGAN system allocates this capacity where needed - invisibly to the end-user. Based on Inmarsat's forecast of traffic and capacity, over a three-minute period we estimate users will consistently experience transfer rates equivalent to more than double those offered by current terrestrial GPRS services.

Other key benefits of Regional BGAN are:

AN INMARSAT NETWORK

Fleet F33 and F55 are the latest additions to Inmarsat's Fleet family of maritime services, designed to equip smaller vessels with voice, e-mail and secure Internet access.

Crews on small and medium-sized boats will now be able to run a mobile office at sea, complete with telephone, e-mail and Internet access, thanks to two new services from Inmarsat.

Called Fleet F33 and F55, the new services follow the successful launch of the first in the family of Inmarsat Fleet services, F77, in April this year.

Together, Fleet F33, F55 and F77 provide high-quality mobile voice and flexible data communications services for the maritime industry. Fleet F55 and F33 allow smaller vessels to benefit from voice, e-mail, secure Internet and intranet access, plus high-quality fax services.

The data rates available through Fleet F33 and F55 mean that a new, wider range of applications is available to the smaller vessel market. Maritime-specific information, such as sea and weather charts, can be made available online and updated in real time. Users can also enjoy the benefit of reliable, easy access to e-mail whenever and wherever needed.

The benefits of Fleet F33, due for launch in early 2003, include:

Fleet F55's data service, on the other hand, will utilize the spotbeams on Inmarsat's satellites, providing up to 64kbit/s Mobile ISDN or Mobile Packet Data in those areas of the world covered. F55 voice services use the global beam to provide worldwide coverage.

The benefits of Fleet F55, due to be launched in early 2003, include:
