Abstract
A method for acquiring a GPS signal includes receiving a GPS signal portion over a coarse acquisition (C/A) frame period. The received GPS signal portion is stored and correlated to each of a plurality of versions of a reference coarse acquisition code to obtain a respective plurality of autocorrelation values. A peak value is selected among the autocorrelation values, the peak value corresponding to a version of the reference coarse acquisition code which is most aligned with the received GPS signal.
