A pedestrian navigation device ( 10 A) of this invention has a position information reception unit ( 12 ), which obtains current position information from a GPS ( 20 ); a position information analysis unit ( 13 ), which calculates the current position by analyzing received current position information; a MAPDB (Map Data Base) ( 14 ), which stores map information; a multi-path control unit ( 17 ), which specifies a multi-path control distance to control multi-path interference; a central processing portion ( 11 ), which calculates current position display information, based on the current position calculated by the position information analysis unit ( 13 ), on map information stored in the MAPDB ( 14 ), and on the multi-path control distance specified by the multi-path control unit ( 17 ); a display unit ( 15 ), which displays current position display information; and an input unit ( 16 ), which inputs distance specification value and route search conditions and issues instructions to begin navigation. By this means, a pedestrian navigation device is provided, which enables to accurately navigate the route of a pedestrian by appropriately correcting the multi-path interference.
