Abstract:
Global Positioning System (GPS) requires the signals from at least four observable satellites with good condition. However, in urban areas, the number of the observable satellites in line-of-sight decreases because urban areas have many buildings. In such case, the position estimation cannot be performed well. In order to estimate even if the good observable satellites are decreased, we use distance sensors. Many vehicles have the distance sensors that can measure traveling distances. In our proposal, the distance sensors assist in calculating own position. By the combination of GPS and the distance sensors, the proposed method can continue robust positioning even if we are in urban areas. Our experimental results will evaluate our effectiveness of the proposal.
