ALEXANDRIA, Va., March 17 -- United States Patent no. 12,578,479, issued on March 17, was assigned to Trimble Inc. (Westminster, Colo.).

"Jamming resistant fast navigation data bits polarity recovery" was invented by Yiming Yu (Cupertino, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "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, ...
