A magnetic ranging aided dead-reckoning indoor positioning system for pedestrian applications

This paper investigates the applicability of a developed magnetic ranging and positioning system (MPS) as a support for a dead reckoning inertial navigation system for pedestrian applications. The integrated system combines the complementary properties of the separate systems, operating over long periods of time and in cluttered indoor areas with partial non-line-of-sight conditions. The obtained results show that the proposed approach can effectively improve the coverage area of the MPS and the operation time with bounded errors of the dead reckoning based system.
