The IEEE Journal of Indoor and Seamless Positioning and Navigation (J-ISPIN) publishes original research in the fields of localization and tracking of people, robots and objects. It covers all aspects of localization systems, including sensing, communications, location-based services, mapping, protocols, human interfaces and standards. The scope includes methods and systems addressing indoor environments as well as those enabling seamless transition between heterogeneous indoor contexts or between indoor and outdoor environments, for example where Global Navigation Satellites Systems are underperforming or unavailable.
