Abstract
A method of acquiring signal code phases includes selecting a correlation sum with a greatest magnitude from a set of correlation sums after a predetermined time has elapsed. A geographic positioning receiver performing the method includes two or more memory banks (114, 116, 118, 120) alternating between storing a signal sequence and transmitting the signal sequence to parallel correlators (132, 134) to be correlated against a predetermined pattern sequence for real-time data processing.
