To realize stable radio communication when remotely monitoring a moving body by radio communication.SOLUTION: A navigation device includes: a position radio quality base station information storage section that stores position radio quality base station information in which a position, radio communication quality, and base station identification information are associated; a cost calculation section that performs weighting on route candidates so that the route candidates are inferiorly evaluated if the radio communication quality is poor on the basis of the position radio quality base station information; a route search section that searches for a route from the weighted route candidates on the basis of the weighting; a radio quality old/new comparison section that compares the radio communication quality of the position radio quality base station information with radio communication quality at the timing when a moving body moves toward a destination; and a radio quality deterioration amount correction section that corrects a radio communication quality deterioration amount for the radio communication quality of the position radio quality base station information on the basis of a comparison result.SELECTED DRAWING: Figure 1

    【課題】無線通信により遠隔で移動体を監視する際に安定的な無線通信の実現を図る。【解決手段】位置と無線通信品質と基地局識別情報とが関連付けられた位置無線品質基地局情報を格納する位置無線品質基地局情報格納部と、位置無線品質基地局情報に基づいて経路の候補に対して無線通信品質が悪いと低評価になるように重み付けを行うコスト算出部と、重み付けがされた経路の候補の中から重み付けに基づいて経路を探索する経路探索部と、位置無線品質基地局情報の無線通信品質に対して移動体が目的地に向けて移動するタイミングの無線通信品質との比較を行う無線品質新旧比較部と、当該比較結果に基づいて位置無線品質基地局情報の無線通信品質に対して無線通信品質悪化量の補正を行う無線品質悪化量補正部と、を備える。【選択図】図1
