Abstract:
In order to estimate a receiver's position, a Global Positioning System (GPS) receiver has to receive the signals from at least four observable satellites. However, in urban areas, the number of the observable satellites decreases because urban areas have many buildings. In such cases, the position estimation cannot be performed well. So, our research considers position estimation in case that the observable satellites are decreased. Many vehicles have the distances sensors which can measure traveling distance. Our proposal can estimate own position by using the traveling distance and the previous position which is estimated under good GPS condition. Our experimental results will show our effectiveness of the proposal.
