|Abstract:||GPS positioning in urban scenarios is challenging because of large numbers of non-line-of-sight outlier measurements. In this paper we propose a robust positioning algorithm that combines GPS observations with visual-inertial odometry information to handle such outliers. We demonstrate the effectiveness of our algorithm in a simulation scenario with close to 80% outliers. In experiments in a mild urban-canyon environment, our approach reduces the 95th percentile horizontal positioning error by 66% compared to a GPS-only solution.|
