Improved GPS Sensor Model for Mobile Robots in Urban Terrain

Abstract [en]

Autonomous robot navigation in outdoor scenarios gains increasing importance in various growing application areas. Whereas in non-urban domains such as deserts the problem of successful GPS-based navigation appears to be almost solved, navigation in urban domains particularly in the close vicinity of buildings is still a challenging problem. In such situations GPS accuracy significantly drops down due to multiple signal reflections with larger objects causing the so-called multipath error. In this paper we contribute a novel approach for incorporating multi- path errors into the conventional GPS sensor model by analyzing environmental structures from online generated point clouds. The approach has been validated by experimental results conducted with an all- terrain robot operating in scenarios requiring close- to-building navigation. Presented results show that positioning accuracy can significantly be improved within urban domains.
