摘要: PROBLEM TO BE SOLVED: To more reduce error of running azimuth at the time low speed running. SOLUTION: In case where a car velocity is comparatively large, processor 1 performs correction for making coincide with traveling azimuth, although absolute value difference between and obtained from GPS receiver small. When small, above only in that large. precision low, it can be judged whether mistaken than or equal to some extent. mistake extent, corrected which has smaller error.
