A position estimation systemaccording to the present disclosure includes a first sensor configured to output first data including data of an angular velocity of a wheel driven when a moving apparatusmoves. The position estimation system further includes a second sensor configured to output second data including position data of the moving apparatusdetected not according to the angular velocity of the wheel or data concerning a change in a posture of the moving apparatus. The position estimation system further includes a self-position estimation unit configured to set a priority of the first data according to a value of the angular velocity of the wheel and integrate the first data with the second data based on the set priority to estimate a position of the moving apparatus
