Abstract :
In this paper, we present a novel position estimation system for moving receivers in urban area. Currently, position estimation systems using at least four GPS satellites are most popular. However, because of the influence of signals shielded by buildings and multipath, measurement error becomes larger. For accurate estimation, we discuss algorithms for position estimation which doesn´t depend on the GPS satellite too much. The proposal uses only one satellite and two receivers. Our approach is to reduce the necessary number of the satellites. Moreover, it is useful for Quasi-Zenith Satellite Systems effectively. In this paper, we introduce the proposal algorithm and the estimation characteristic derived from computation simulations.
