In 1999,the U.S. government announced GPS modernization plan.CNAV message will be broadcast in the new navigation signals L2C,L5, which is differs from NAV message in channel encoding.Aim at the high error rate of the conventional channel decoding process of CNAV message, this paper proposes an improved channel decoding based on characteristic information and realize channel decoding accurately.
