| Abstract(in English) | GPS positioning is calculated from the pseudo range calculated by the observed propagation time between GPS satellites and GPS reception point. However, when reflected GPS signals are received, pseudo ranges longer than original linear distances are observed, so they would degrade GPS positioning accuracy especially in urban areas surrounded by many tall buildings. In order to solve this problem, the pseudo range correction has been proposed. It needs the numbers of reflections and the incident angles of the received GPS signals at GPS reception points, and the distances between the building reflection surface and GPS reception points. In the previous studies, in a simple north-south axis linearly symmetric simulation model, the numbers of reflections and the incident angles have been estimated, and the distances from the building reflection surface have been evaluated as known values. In this paper, the numbers of reflections and the incident angles have also been estimated in the simulation model established by Shinjuku area environments. Moreover, the distances between the building reflection surface and GPS reception points have actually been measured by a commercial laser range finder in Shinjuku area. It is evaluated that the pseudo range correction can improve GPS positioning errors even in the Shinjuku model. |
