ABSTRACT:
A vehicular traveling direction measuring system derives a weighting constant based on a monitored magnitude of the geomagnetic disturbance around a vehicle. Variance values of geomagnetism indicative data and a deviation magnitude from a standard azimuth circle may be used to estimate the geomagnetic disturbance magnitude. Mean data is derived from current cycle data and prior cycle data of the monitored geomagnetism using the weighting constant. The weighting constant determines a rate of dependency upon the current cycle data and the prior cycle data when deriving the mean data. The vehicular traveling direction is derived based on the derived mean data.
