To perform high-accuracy positioning with easy processing using positioning signals from a plurality of positioning systems.SOLUTION: A positioning device 10 includes reception units 31, 32, and 33, and a positioning computation unit 40. The reception units 31, 32, and 33 detect pseudo distance or a carrier wave phase integrated value of positioning signals from a plurality of positioning systems. The positioning computation unit 40 sets a statistical computation value of each position of the positioning systems as an integrated position, sets a statistical computation value of each error covariance as an integrated error covariance, performs Kalman filter processing, and thereby performs positioning.SELECTED DRAWING: Figure 1
【課題】複数の測位システムの測位信号を用いて、容易な処理で高精度な測位を行う。【解決手段】測位装置10は、受信部31、32、33、および、測位演算部40を備える。受信部31、32、33は、複数の測位システムの測位信号の擬似距離または搬送波位相積算値を検出する。測位演算部40は、複数の測位システムの各位置の統計的演算値を統合位置とし、各誤差共分散の統計的演算値を統合誤差共分散として、カルマンフィルタ処理を実行することによって、測位を行う。【選択図】 図1
