摘要: Accurate and reliable vehicle localization with GPS is an important part of many automotive applications. Unfortunately, in urban areas multipath a major source for positioning errors. While this can be handled expensive equipment, vehicles sensor budget usually limited, so other approaches are to preferred as well. This paper aims evaluate mitigation technique based on cheap hardware combined 3D environment model. model shall map surrounding obstacles like buildings the terrain that impair received signals. As result, used within Bayesian implementation filter improve accuracy integrity.
