Abstract: A position correction device includes: a reception unit, a position acquisition unit, a determination unit and a position information transmission unit. The reception unit receives a position information S1 of a vehicle from a navigation apparatus. The position acquisition unit acquires a position information S2 of the vehicle with a higher accuracy than the navigation apparatus. The determination unit determines whether a difference between the position information S1 and the position information S2 exceeds a predetermined threshold, or determines whether a traveling road identified by the position information S1 matches a traveling road identified by the position information S2. At least when it is determined that the difference exceeds the threshold, or when it is determined that the identified traveling roads do not match, the position information transmission unit transmits the position information S2 to the navigation apparatus.
