ABSTRACT:
A vehicle position calculating apparatus has relative position calculating means for calculating a relative vehicle position with respect to a reference position and absolute position calculating means for calculating an absolute vehicle position from fixed-station absolute position information and vehicle bearing information which are obtained from a radio wave transmitted from a fixed station and the above-described relative vehicle position. The relative position calculating means includes means for calculating a present vehicle position by employing absolute positions successively obtained as new reference positions. Accordingly, it is possible to accurately obtain an absolute present vehicle position.
