ョン装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a plurality of GPS (Global Pos.
The present invention relates to a vehicle navigation device that receives satellite radio waves from a satellite and calculates the position of a vehicle.
［従来の技術］

動車の位置を演算し表示するＧＰＳシステムによる車両
用ナビゲーション装置か開発されている。[Prior Art] Vehicle navigation devices using a GPS system have been developed that receive satellite radio waves from a plurality of GPS satellites to calculate and display the position of a vehicle.
例えば、複数のＧＰＳ衛星から衛星電波をそれぞれ受信
し、ＧＰＳ衛星の軌道データ等から自動車の位置を演算
し表示する車両用ナビゲーション装置は、自動車の走行
時に現在走行している位置を随時自動車の運転者等に報
知する上で有意である。For example, a vehicle navigation device that receives satellite radio waves from multiple GPS satellites, calculates and displays the vehicle's position from the orbit data of the GPS satellites, etc. This is significant in informing people, etc.
また、従来、車両用ナビゲーション装置とじては、■単

独航法型ＧＰＳによる装置が示されている。For example, in Japanese Patent Application Laid-Open No. 63-91582, rGPS
As a "navigation device", a single navigation type GPS device using so-called map matching is shown.

波の電離層遅延、大気屈折等による誤差が含まれている
。Generally, in a single navigation type GPS, the distance between the vehicle and the GPS satellite is determined by receiving satellite radio waves from the GPS satellite, and the current traveling position of the vehicle (GPS positioning data) is determined from this distance. Here, the calculated distance includes errors due to ionospheric delay of satellite radio waves, atmospheric refraction, etc.
前記公報に示される装置においては、このような誤差を

As a result, the driving position of the vehicle can be determined with an accuracy at least equivalent to the interval between intersections.
