method for acquiring a plurality of gps signals , in which the signals received from the space vehicles are correlated , in an array of parallel processing modules with local replicas of a pseudorandom code . the local pseudorandom code generators are slewed periodically , on detection of an external periodical trigger int_acc , and the correlation data are dumped simultaneously to all processing modules in output registers for acquisition and tracking software . the integration period is shorter than the natural period of the pseudorandom code sequence , and all the local generators are slewed at the same time , thereby allowing a quicker acquisition of the sv c / a code .
