SATELLITE-BASED LOCATION SYSTEM EMPLOYING KNOWLEDGE-BASED SEQUENTIAL SIGNAL SEARCH STRATEGY

摘要

Disclosed is a method and apparatus for facilitating detection of satellitesignalsusing a sequential search technique. The sequential search technique is aknowledge basedtechnique that sequentially searches for satellite signals based on searchmessages andinformation accumulated during prior searches to effectively reduce the areaand code phasesearch range in which a GPS receiver searches for the satellite signals,thereby enhancingdetection of the satellite signals.
