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.
