Abstract: A receiver for satellite navigation includes a signal processor for deriving from a satellite signal a pseudorandom sequence of code chips, a converter for producing a digitized version of the received PRN sequence, a first and second shift register (3, 7), a code generator (4), a set of correlators, circuitry for summing correlation values and circuitry for determining a maximum of the summed correlation, and a scheduler (20). The receiver includes at least one multiplexer (6, 24), configured to transform multiple PRN sequences into an interleaved sequence and to enter the interleaved sequence into the first or second shift register (3, 7). The summing circuitry has multiple summing circuits (11) for separately summing correlation values related to the multiple PRN sequences. The circuitry for determining a maximum is configured to determine the maximum in one or more subgroups of sums determined by the multiple summing circuits (11).
