The invention relates to a cyclic redundancy check codes (CRC)-based method for correcting satellite navigation message errors, and belongs to the technical field of satellite navigation. The method comprises the following steps of: constructing a CRC check module, then constructing a CRC error correcting code table, performing error pattern detection according to the CRC error correcting code table, and performing error correction on correctable error patterns obtained by detection. By the method, whether the message is error can be checked, and 1bit error patterns in the error navigation message can also be corrected; compared with the application condition that the CRC error correction is not used, the method has the advantages of effectively reducing the frame error rate of the navigation message, improving the continuity of positioning under weak signal conditions and improving the positioning performance; and the method is suitable for a random satellite navigation system using the CRC as navigation message check errors.
