VEHICULAR C TO THE THIRD POWER N - GLOBAL SATELLITE SOLUTION. IN: CONFERENCE RECORD OF PAPERS PRESENTED AT THE FIRST VEHICLE NAVIGATION AND INFORMATION SYSTEMS CONFERENCE, TORONTO, ONTARIO, CANADA - SEPTEMBER 11-13, 1989

The use of satellites for command, control, communications and navigation is an area of technology which has grown significantly over the last decade and been primarily dominated by the military. The advent of mobile satellite services now offers the public and commercial fleet operators the opportunity to take advantage of these developments. INMARSAT is an international organization whose purpose is to provide the satellite system required to support mobile communications and radio determination services wherever there is a need throughout the world. Established in 1979, it now comprises 56 member countries and since 1982 has operated a global network of L-band satellites. These provided services first for ships, then aircraft and now, with the recently agreed amendments to its convention, is in a position to service the needs of the land mobile user throughout the world. INMARSAT provides services conforming to agreed international standards which enables the mobile to roam and operate throughout the world subject only to national licensing requirements where applicable. This benefits the user whose single terminal can now service a universal requirement thus significantly reducing operating costs. This also enables manufacturers to build for a larger market where economies of scale can make a dramatic impact on production costs of user hardware. The INMARSAT Standard-C System is the cornerstone of its entry into land mobile communications. Equipment is now being produced by manufacturers throughout the world to technical standards set by INMARSAT. This does not inhibit innovative design or applications but ensures that all makes of equipment operate satisfactorily through the satellites and fixed earth stations which provide access from the mobile to the public and private telecommunications networks. Pre-operational service began in the second quarter of 1989 in the Atlantic Ocean and is being extended to the Pacific in the latter part of the year. This is enabling users and manufacturers to gain early experience with the system throughout most of the world prior to full global commercial service being available towards the end of the year. The range of Standard-C capabilities includes two-way store and forward data/messaging; a short burst transmission mode for position and data reporting; polling and an enhanced group call facility. The first four new INMARSAT second generation satellites is scheduled for launching during 1990 and their enhanced capabilities will provide the land mobile user with an even greater range of services in the early 1990s.
