Abstract
A location system acquires a first set of Global Navigation Satellite System (GNSS) satellites from a first set of raw GNSS signal data received by a GNSS receiver, using all of the coarse acquisition (C/A) codes for the system of GNSS satellites, to determine a first set of GNSS satellites to use for location processing. At a later time, the location system determines respective sets of GNSS satellites as subsets of successive sets of previously determined sets of GNSS satellites. When the number of identified satellites is less than a threshold, the location system again acquires a set of GNSS satellites from raw data using all of the C/A codes for the system of GNSS satellites.
