NAVIGATION TERMINAL, NAVIGATION METHOD AND NAVIGATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a navigation terminal capable of improving navigation accuracy when passing through a place where GPS positioning is difficultly performed on a guide route.

SOLUTION: The navigation terminal includes: means for acquiring route guide data from a navigation server; means for acquiring basic information for calculating the current location of the navigation terminal; means for outputting a route guide and the current location based on the acquired basic information and the route guide data; and means for determining whether the coordinate of the current location is within a prescribed range from a coordinate of a destination place of the route guide in the case where a first hierarchical level and a second hierarchical level are set on an object route of the navigation according to reception levels of GPS radio waves, and determining the user has reached the destination when determining that the coordinate of the current location is within the prescribed range on a condition that a hierarchical level of the current location matches a hierarchical level of the destination.
