Abstract
A narrow correlation system is provided for narrow correlation tracking by fixed or dynamic delay of a received encoded signal and correlating the encoded signal and the delayed encoded signal with identical PRN code sequences with coincident epochs to produce early and late correlations separated by substantially less than one code chip, and with multiple correlation points obtained by implementing multiple delays of the encoded signal and separately correlating each different one of the delayed encoded signals with the same PRN code to produce a weighted tracking error signal.
