MOBILE SATELLITES FOR NAVIGATION AND COMMUNICATION. NAV 85 - LAND NAVIGATION AND LOCATION FOR MOBILE APPLICATIONS - PAPERS PRESENTED AT THE 1985 CONFERENCE OF THE ROYAL INSTITUTE OF NAVIGATION, YORK, 9-11 SEPTEMBER 1985

The Federal communications commission in the US is likely to authorise a mobile satellite system that will provide a variety of voice data and position fixing services which will give universal coverage for land vehicles, aircraft and inland and coastal vessels. A commercial company will be chosen to build and generate the system which must also be compatible with that of Canada. The services that could be provided by one such system, mobilesat, are listed and include mobile radio telephone, one and two-way radio dispatch, rural residential telephones, pay telephones for passengers in transit and paging (voice services) and two-way alpha-numeric messages, vehicle location and tracking, remote monitoring and alarm, narrowband and wideband data transmission, facsimile, telegraph communications and slow-scan video (data services). The demand for such services has been studied and is predicted in terms of 'standard equivalent circuits'. The arrangement of the system is described and includes satellites at 2 locations with 'gateways' at strategic locations. Current commercial satellites would be used for the first generation mobilesat system. Details are given of these and proposed second generation satellites. Position location services can be provided either by dependent surveillance, independent surveillance or a hybrid of the two and accuracy can be to within 200 metres. (TRRL)
