Abstract
The motivations, the design, and some applications of the new Pedestrian Dead Reckoning (PDR) navigation device, ULISS (Ubiquitous Localization with Inertial Sensors and Satellites), are presented in this paper. It is an original device conceived to follow the European recommendation of privacy by design to protect location data which opens new research toward self-contained pedestrian navigation approaches. Its application is presented with an enhanced PDR algorithm to estimate pedestrian’s footpaths in an autonomous manner irrespective of the handheld device carrying mode: texting or swinging. An analysis of real-time coding issues toward a demonstrator is also conducted. Indoor experiments, conducted with 3 persons, give a 5.8% mean positioning error over the 3 km travelled distances.
Highlights
More and more Internet of Things applications are based on connected objects carried by human
It is well known that Dead Reckoning (DR) processing of inertial, magnetic, and other signals from selfcontained navigation and positioning solutions follows the concept of “privacy by design” since the measurements do not depend on the access to local infrastructure
The adopted strategy uses the pulse per second (PPS) output of the GNSS receiver embedded in our navigation units to time-tag each sample within one micro second
Summary
More and more Internet of Things applications are based on connected objects carried by human. It is well known that Dead Reckoning (DR) processing of inertial, magnetic, and other signals from selfcontained navigation and positioning solutions follows the concept of “privacy by design” since the measurements do not depend on the access to local infrastructure These signals are available everywhere, supporting the development of a ubiquitous localization technology. This motivated us to develop new hardware to support research on personal navigation which is based on pedestrian DR technologies and meets usage and size factors for conducting real-life experiments. The first one targets research activity on personal geolocalization systems and methods with handheld object It is a unit called ULISS, for Ubiquity Localization with Inertial and Satellite System, which is presented along with its applications in the rest of the paper. It is called PERSY, for PEdestrian Reference System, and its accuracy is about ten times better than ULISS
