    • A position locating system and method are provided for determining a geographic location of a portable remote unit. The locating system includes a communications system having at least one base station and a system controller. The base station bi-directionally couples the remote unit to the system controller through wireless links. The locating system also includes a server coupled to the system controller by a communication infrastructure external to the communications system. The server includes a data store which contains satellite positioning information. In response to a message from the remote unit, the server provides satellite information to the system controller over the communication infrastructure such that the provided satellite information is passed to the remote unit by the base station. The provided satellite information includes information to aid in acquiring a predetermined number of satellites within a satellite positioning system. The acquired satellites provide coded signals for determining the geographic location of the remote unit. In one embodiment, the data communication system is a cellular telephone network and the communication infrastructure is the Internet. The Internet is coupled to the cellular telephone network through a public switched telephone network (PSTN).
    • 提供了一种用于确定便携式远程单元的地理位置的位置定位系统和方法。 定位系统包括具有至少一个基站和系统控制器的通信系统。 基站通过无线链路将远程单元双向耦合到系统控制器。 定位系统还包括通过通信系统外部的通信基础设施耦合到系统控制器的服务器。 服务器包括一个包含卫星定位信息的数据存储。 响应于来自远程单元的消息,服务器通过通信基础设施向系统控制器提供卫星信息,使得所提供的卫星信息由基站传递到远程单元。 所提供的卫星信息包括有助于获取卫星定位系统内的预定数量的卫星的信息。 所获取的卫星提供用于确定远程单元的地理位置的编码信号。 在一个实施例中,数据通信系统是蜂窝电话网络,并且通信基础设施是因特网。 互联网通过公共交换电话网(PSTN)耦合到蜂窝电话网络。
