Abstract
A disclosed vehicle control device includes a first ionospheric state information receiving unit receiving information of a predicted ionospheric state at a time point later than a current time point; a second ionospheric state information receiving unit receiving information of an ionospheric state at the current time point; an ionospheric delay error estimating unit estimating an ionospheric delay error by correcting a first ionospheric delay error based on a second ionospheric delay error, the first ionospheric delay error being derived based on the first ionospheric state information, and the second ionospheric delay error being derived based on the second ionospheric state information; and a positioning unit locating a position of a moving body based on a receiving result of a radio wave from a satellite and the estimated ionospheric delay error.
