Abstract: A position determining system (PDS) receiver gathers independent location information from multiple sources. These multiple pieces of location information are analyzed to determine consistency of location. If the location is consistent among the various independently gathered location information, then the location information is injected into the PDS positioning process for more efficient acquisition and positioning. Otherwise, if inconsistency is found, then no location information is injected into the PDS positioning process.

Abstract: In a radio frequency (RF) receiver, a receiver RF chain is tuned to a first (e.g., global positioning system (GPS)) channel to permit receipt of a first (e.g., GPS) signal over the first (e.g., GPS) channel on the receiver RF chain during a first time duration. The receiver RF chain is tuned to a second (e.g., cellular page) channel to permit receipt of a second (e.g., cellular page) signal over the second (e.g., cellular page) channel on the receiver RF chain during a second time duration, following the first time duration. The first (e.g., GPS) signal is processed during the first time duration and the second time duration, without any apparent interruption of the first (e.g., GPS) signal during the second time duration. The processing, for example, treats the actual interruption as a temporary, short term fade of the first (e.g., GPS) signal during the second time duration, or provides a bridge signal (e.g., an estimated GPS signal on the receiver RF chain or an actual GPS signal received on another receiver RF chain) during the second time duration.

Abstract: A parameter estimator for estimating one or more parameter(s) from a correlation function derived from a signal using a dynamically variable search window is described. The parameter estimator may be employed in a subscriber station to estimate the time of arrival of one or more base station pilot signals in a wireless communication system. This information may be utilized in an overall advanced forward link trilateration (AFLT) process for estimating the location of the subscriber station.
