  • Abstract
    The GlobalstarTM system provides telephone and data services to mobile and fixed users between ±70° latitude. Connections are made from the mobile user to one of a group of fixed terrestrial gateways via a constellation of low Earth orbiting satellites (LEOs). Globalstar uses an extension of the CDMA, IS-95 standard used for cellular systems. The satellite link is sufficiently different from the terrestrial link that certain departures from IS-95 were needed both in signal design and in system operation. This paper describes some ofthe similarities and differences with IS-95
