ABSTRACT:
System and method for enabling signal acquisition in a satellite positioning system (SPS) when signals from SPS satellites are attenuated by the operating environment of a SPS receiver. A preferred embodiment comprises a communications server (for example, communications server220) coupled to a SPS receiver (for example, SPS receiver210) at one end and a time server (for example, time server225) by a public network (for example, the Internet230). Preferably, the communications server220is coupled to the Internet230via a wireless network to facilitate maximum mobility and flexibility. The communications server220queries the time server225for the current time and then provides the current time to the SPS receiver210. The SPS receiver210makes use of the current time to assist it in signal acquisition.
