| Abstract(in English) | From the point of view of safety applications, accurate and reliable positioning of road users is the most important part. Although GPSs are the most widely utilized technology today, they still have the problems of performance degradation caused by multipath propagation in urban canyons. Excluding suspicious signals is effective to reduce the effect of multipath, however, it may lead lack of satellites.This study proposes an approach to estimate position by searching around the result of GPS output. The proposed algorithm evaluates the pseudoranges of the possible multipath signals by referring to the building geometry. Position assumptions are evaluated by the likelihood of the possible positioning error and filtering algorithm. The proposed method was verified through field experiments in urban canyons in Tokyo and has achieved improvements in precision and accuracy. |
