Over the past 15 years, there has been an exponential growth of new technologies for indoor positioning and navigation. Unlike GNSS technology, which has become the leading solution for outdoor positioning, no technology has taken the lead indoors. With the price drop of radio beacons, we see massive deployment of beacons’ networks for positioning. Image processing is progressing fast thanks to machine learning techniques that improve the rendering of very low-cost cameras. More and more smart devices embed inertial sensors providing autonomous navigation options. These are only a few of the technologies deployed. Hybridizing technologies to find the best compromise between accuracy, cost and energy consumption is at the heart of ongoing development. The nature of sensors in the infrastructure or smart devices, specific use cases requirements and privacy concerns about geolocated data are all features used to choose the right technologies to hybridize. Adopting a ubiquitous approach that combines dead reckoning and absolute positioning while recognizing the application and environmental context is certainly a strong trend in current developments and research. Given the great diversity of existing positioning systems and ways of presenting their performance, it seems almost impossible to provide a clear comparison of localization performance. The key to this comparison certainly lies in experimental comparative trials, in the same context and on identical scenarios. This approach started several years ago with international positioning competitions. This talk will review main indoor positioning technologies according to several comparison criteria. It will also exploit the results of the 2018 Indoor Positioning Indoor Navigation(IPIN) international competition that took place in a 9’000m²shopping mall (Atlantis) in Nantes (France) where 49 teams competed.
Dr. Valérie Renaudin is a Research Director at Université Gustave Eiffel. She has an M.Sc. degree in geomatics engineeringand a PhDdegree in computer, communication, and information sciences. She was a Technical Director at Swissat Company, Switzerland, developing real-time geopositioning solutions based on a permanent global navigation satellite system (GNSS) network, and a Senior Research Associate with the PLAN Group, University of Calgary, Canada. She is currently leading the Geoloc Laboratory (GEOLOC), where she built a team on positioning and navigation for travelers in multimodal transport. Her research interests include outdoor/indoor navigation using GNSS, and inertial and magnetic data, particularly for pedestrians to improve sustainable personal mobility. She is a member of several journals editorial boards and the steering committee of the international conference on « Indoor Positioning and Indoor Navigation ». Dr. Renaudin was also the recipient of the European Marie Curie CIG grant in 2013 and the ANR labcom inmob grant in 2020.
