Abstract
A method and apparatus are provided for performing consistency testing for a Bose-Chaudhuri-Hocquenghem (BCH) error corrected first sub-frame of navigation message broadcast from a satellite of a GNSS. Consistency testing is performed by comparing BCH encoded portion(s)s of data symbols with elements of look up table(s) to see if such portions are similar to element(s) of the look up table(s).
