A vehicle navigation system and storage medium for determining an estimated position of a vehicle. The system and storage medium comprises at least an input unit, a present position detection unit, a storage unit, a central processing unit, an information transmission/reception unit and an output unit. Information concerning route guidance is input, as is present position detected information, and stored such that calculation of an estimated position of a vehicle may be generated based on a variety of conditions such as vehicle speed history, elevation angle of a satellite position relative to the vehicle, and penalty values attributed to the types of roads traveled.
