摘要：
The GIobalstar(TM) System provides telephone and data service to mobile and fixed users between +/-70 degrees 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(2) 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 of the similarities and differences with IS-95.
