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 server) coupled to a SPS receiver (for example, SPS receiver) at one end and a time server (for example, time server) by a public network (for example, the Internet). Preferably, the communications serveris coupled to the Internetvia a wireless network to facilitate maximum mobility and flexibility. The communications serverqueries the time serverfor the current time and then provides the current time to the SPS receiver. The SPS receivermakes use of the current time to assist it in signal acquisition.
