The Use of GPS for Handling Lack of Indoor Constraints in Particle Filter-Based Inertial Positioning

Particle filter-based inertial positioning promises infrastructure-less positioning, but previous research have not provided an understanding of, how the positioning accuracy of such systems depends on the layout of building structures. This poster presents initial result for the impact of the layout of building structures on the positioning accuracy using a particle filter-based inertial positioning system named Pro-Position. We also consider methods for using GPS positioning with particle filter-based inertial positioning to improve accuracy in areas, where positioning is poor because of lack of constraints from the layouts of the building structures.
