Abstract
An apparatus (200) for determining time within a global navigation satellite receiver comprises a correlator (1), a combiner (35, 37), a comparator, and a processor. The correlator (1) comprises a means for determining a common data pattern between received signals of at least two satellites, and a means for calculating a dot product (15) for each of the at least two received signals. The combiner (35, 37) combines the calculated dot products to generate a combined dot product result. The comparator (41, 43) compares the combined dot product results with the common data pattern to generate a comparing result. The processor (47) determines a time from the comparing result.
