Abstract:

Without proper GPS signals, indoor navigation is still an ongoing research topic. As part of the PiNav Project, this thesis's target is to improve the the localization quality of the system. First, a new sensor box is programed that is equipped with more precise inertial sensors than the old one, so that the dead reckoning system can operate on a more accurate data basis. Second, a magnetic map is implemented that allows incorporation of absolute position information into the algorithm. Additionally, a novel mapping algorithm is presented, that is specially designed for the needs of the current system. Namely this means only a rough position estimation and limited processing power.
