Abstract
Disclosed is a method and apparatus for facilitating detection of satellite signals using a sequential search technique. The sequential search technique is a knowledge based technique that sequentially searches for satellite signals based on search messages and information accumulated during prior searches to effectively reduce the area and code phase search range in which a GPS receiver searches for the satellite signals, thereby enhancing detection of the satellite signals.
