With timely and reliable satellite data communications, ships can also send and receive a variety of business reports such as changes in manifests, navigational charts, orders for spare parts and sup- plies, bay and crew reports...to name just a few.

Inmarsat-A, an analog service, was inaugurated by Inmarsat in 1982, bringing first-class tele- phone calling to the maritime and mobile communications environ- ment. Demand for international data services is spurring growth of digital satellite terminals, known in the industry as Inmarsat-B ter- minals. These B terminals are the digital successors to Inmarsat-A terminals.

The digital communications ser- vice provided by COMSAT, known as COMSAT-B, began in 1993.

Until now, this service has largely been overshadowed by COMSAT-

A. However, this is rapidly chang- ing because COMSAT-B, which makes more efficient use of radio spectrum, costs about 30 percent less than A.

In addition to the cost savings, B voice quality is now comparable to the voice quality users have become accustomed to with A.

There is also very little difference in terminal size. The maritime

Inmarsat-B terminal is 1,244 mm (49 in.) x 1,350 mm (53 in.). Land- mobile terminals can be even smaller, with some full-function terminals as light as 13 kg (29 lbs.) and small enough to be taken on airplanes as carry-on luggage.

According to Inmarsat, the pri- mary users of B services are mar- itime related including merchant shipping, energy exploration, fish- ing and government. For land- mobile use the largest markets are equipment (rental/resale) agents, the media, energy exploration, and government. In the offshore mar- ket, Inmarsat-B terminals are averaging 30 minutes of voice traf- fic per day. There are more than 5,000 Inmarsat-B terminals oper- ating in the Inmarsat system today; approximately 55 percent of these are maritime and 45 percent are land mobile. Inmarsat projects

SATELLITE COMMUNICATIONS cost (' l"l I CI

Cerent ways to communicate.

Different satellite services offer some combination of fax. voice, data or telex. Of all these offer- time. because it is the newest option for sailors at sea. there is still a lot of mystery about why and how to use a data transmis- sion service.
