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 Sof a vehicle from a navigation apparatus. The position acquisition unit acquires a position information Sof the vehicle with a higher accuracy than the navigation apparatus. The determination unit determines whether a difference between the position information Sand the position information Sexceeds a predetermined threshold, or determines whether a traveling road identified by the position information Smatches a traveling road identified by the position information S. 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 Sto the navigation apparatus.
