the best solutions for maritime satellite communications

Inmarsat -B.

The Inmarsat-B Digital mobile satcoms system provides two-way direct-dial phone, fax, telex and data communications at rates up to 9.6kbit/sec to and from anywhere in the world with the exception of the polar regions. An Inmarsat B terminal is a small self-contained satellite earth station comprising, in the maritime environment, of an above deck equipment containing a parabolic antenna and electronics and a below deck equipment containing electronic units, power supplies and interface connections. Connections to telex, telephone, modem and facsimile equipment are contained in the below deck equipment.

Inmarsat -C.

Inmarsat-C is the most efficient system for store and forward text messaging available, as well as for telemetry and tracking, at remarkably low operational cost. Inmarsat-C is globally acknowledged by International Maritime Organization (IMO) as a complete maritime safety and distress system according to Global Maritime Distress and Safety System (GMDSS) requirements. The GMDSS is an internationally agreed-upon set of safety precedures, types of equipment, and communication protocols used to increase safety and make it easier to rescue distressed ships, boats and aircraft. It is not possible to use this system for any voice communication. The following services are available via the Inmarsat-C network:

Store-and-forward messaging services : The Inmarsat-C network can be used for sending different types of store-and-forward messages: ■ Telex message service. ■ Fax messaging service. ■ Messages to and from a computer. ■ e-mail service. ■ Ship-to-ship communications.

Distress alerting and distress priority messaging

Inmarsat Fleet 33.

Inmarsat Fleet 33 offers integrated voice, fax and data as well as the Mobile Packet Data Service (MPDS), allowing end-users to remain "always connected". Charges are made for the amount of data sent and received rather than the time spent online. Ideal for e-mail, web and intranet access.

The system allocates global coverage and provides: Voice 4.8 kbps (Inmarsat Mini-M quality) ■ Fax at 9.6 kbps ■ Data at 9.6 kbps ■ Mobile Packet Data Service (MPDS).

Inmarsat Fleet 55.

Whatever your needs, Inmarsat Fleet 55 offers a single, integrated communica-tions solution that delivers versatility and choice to ensure that you and your vessel are no longer isolated while at sea. Because Inmarsat Fleet Fleet 55’s antenna and be-low deck unit package is smaller and more economical than the Fleet 77 equivalent, Fleet 55 is suitable for use onboard a wide range of vessels, including medium-sized merchant ships, large motor and sailing yachts, larger fishing vessels, patrol boats, research vessels, survey ships and offshore support craft.

Voice Services : Inmarsat Fleet 55 provides digital voice communications on a virtually global basis as standard with a 4.8kbps voice channel. A high quality 3.1kHz audio channel is also available.

Fax Services : Inmarsat Fleet 55 ISDN channel enables 64kbps Group 4 Fax for vessel-to-shore, shore-to-vessel and vessel-to-vessel applications. A 9.6kbps Group 3 Fax option is also provided.

Data Services : Inmarsat Fleet 55’s key differentiator is its ability to deliver high-speed Internet Protocol (IP) data transmissions. The service’s Mobile ISDN channel offers data transfer rates of up to 64kbps. Mobile ISDN enables users to send and receive e-mail, access virtual private networks (VPNs), transfer large data files and digital images, as well as run live videoconference.

Inmarsat Fleet 77.

The Inmarsat Fleet 77 system is one of the most advanced satellite telecom services dedicated to the maritime industry. It was developed so that, on the one hand it would take full advantage of the existing satellite telecommunications infrastructure as well as any new technological developments and on the other hand, to cover all the specialised requirements of modern maritime industry.
It combines every service currently offered from the existing telecom networks, together with new enhanced services as dictated by the contemporary business environment. Thus, it offers the traditional forms of telecommunications such as voice, fax and e-mail, with the most up to date services such as transmission of electronic video and audio files at high speeds (128 or 64 kbps). Furthermore, the system possesses unique characteristics, such as the capabilities to be "on-line" with the IP network on a 24/7 basis, on a volume-based charge, subject to usage.
Inmarsat Fleet 77 is fully compliant with the most updated specifications of the International Maritime Organisation (IMO) for new systems introduced to the international safety and distress system (GMDSS), providing prioritisation and pre-emption.

The system allocates global coverage and provides : Speech 128 or 64 kbps ■ Voice 4.8 kbps (Inmarsat Mini-M quality) ■ Data transfer 128 or 64 kbps (UDI) ■ Data transfer 56 kbps (V110) ■ High quality audio at 3.1 kHz (ISDN) ■ Mobile Packet Data Service (MPDS) ■ Fax 2.4 kbps or 9.6 kbps or 64 kbps (fax G4).

BGAN

Inmarsat’s Broadband Global Area Network (BGAN) is the world’s first mobile communications service to provide both voice and broadband data simultaneously through a single, truly portable device on a global basis. It is also the first to offer guaranteed data rates on demand.
In a standard office environment, broadband access is now taken for granted. But for those whose jobs take them away to more remote locations, accessing the corporate network or the internet often means a return to slow dial-up connections, or worse still, no access at all. With Inmarsat’s BGAN service, you can set up a broadband mobile office in minutes – wherever you are on the planet.
With a single BGAN device, you can access data applications at speeds up to half a megabit and make a phone call at the same time.

Phone : Make phone calls at the same time as accessing your data applications.

Standard IP :: For e-mail, internet and intranet access via a secure VPN connection, at speeds up to 492kbps over a shared channel.

Streaming IP: Guaranteed data rates on demand up to 256kbps.

SMS : Send and receive text messages via your laptop – up to 160 characters – to or from any mobile phone.

ISDN : BGAN also supports ISDN at 64 kbps depending on BGAN terminal type.

Fax : Fax services supporting via 3.1 kHz channel depending on BGAN terminal type.
