Abstract:
A Global Navigation Satellite System (GNSS) device, such as the Global Positioning System (GPS) device, uses satellite orbital position information from almanac and/or ephemeris data to change a search parameter, such as reducing the number of analyzed frequency bins or setting signal strength threshold, so that satellite signal acquisition times are reduced. An exemplary embodiment estimates an orbital position for at least one GNSS satellite based upon at least one of almanac data and ephemeris data, detects a signal emitted from the at least one GNSS satellite, and based upon the estimated orbital position information for the at least one GNSS satellite that is determined from the almanac data and the ephemeris data, adjusts at least one parameter used in the analysis of the detected signal.
