Abstract: A method for reducing the risk of jamming during determination of the polarity of navigation bits in a GNSS signal. More than a threshold number of 1s or 0s are considered to be jamming data, and are ignored in two areas. First, they are ignored in generating a lookup table when determining which bits are historically risky bits in navigation acquisition. Second, they are ignored during a current navigation acquisition, since such bits may be due to current jamming efforts.
