<p>To provide a vehicle navigation system which can accurately display a position of a vehicle with the navigation system mounted thereon and a target direction even when the vehicle is stopped or traveling at low speed. A vehicle navigation system includes a unit sensing a traveling state of a vehicle, a unit judging whether or not the vehicle is stopped or traveling at low speed, and a unit smoothing GPS positioning data so that error components contained in the GPS positioning data are canceled with each other or compensated when the vehicle is stopped or traveling at low speed. The navigation system further includes a unit calculating the current position based on the smoothed GPS positioning data. The smoothing unit outputs new positioning data, for example, based on current GPS positioning data and previous GPS positioning data.</p> |
