ABSTRACT:
A method and apparatus is disclosed for adaptively processing Global Positioning System (GPS) signals in a GPS receiver. An adaptive method of processing GPS signals optimizes the initial acquisition of GPS signals by performing the search using three separate parameters. These parameters include satellite number, Doppler information, and integration time. A block processing method of GPS signal processing is performed for particular in-view satellites over particular time intervals and for each of a set of hypothesized Doppler frequencies. Each parameter is optimized such that the GPS signal acquisition operation for a location fix is performed in a short period of time.
