For a precision approach and landing system of aircraft using GPS, it is nessessary to improve the system performance such as positioning accuracy, integrity, continuity and availability. A possible way for improving the performance may be to use pseudolites (pseudo-satellites) located on the ground near airport in addition to ordinally GPS satellites. In this paper, a qualitative simulation was carried out for evaluating positioning accuracy for the approaching aircraft using pseudolites together with the existing GPS satellites. Flight experimental data and artificial data on ranging measurement were used for the simulation. The result shows that while the positioning accuracy strongly depends on relative location of pseudolites, GPS satellites and the aircraft, the accuracy can be improved by the utilization of pseudolites.
