Tutorial 1 : Radio Map Construction Methods for Global Indoor Positioning System

Speaker: Prof. Dongsoo Han(KAIST)

Course Level: Beginner to Intermediate

A radio map is a collection of fingerprints with their collected location information. It is one of essential components to realize a global indoor positioning system (GIPS). However constructing radio maps for most of the buildings in villages and cities all over the world requires tremendous time and efforts. There has been many attempts to reduce the cost of constructing the radio maps, but it is still an unaddressed problem. This tutorial introduces various radio map construction methods, such as point-by-point manual calibration method, walking survey, GPS-based method, address-based method, and reference-free unsupervised learning method. The benefits and drawbacks of each method will also be discussed in this presentation.

Dongsoo Han is Professor of Computer Science at KAIST. Dongsoo Han’s group, in collaboration with KTNET, built an indoor positioning and navigation system at COEX in 2010, and KAIST Indoor Localization System (KAILOS) to realize an indoor GPS system in 2014. In 2011, Dongsoo Han founded the indoor positioning research center(IPRC) at KAIST. Dongsoo Han is serving as director for the IPRC. In 2013, Dongsoo Han published the book “Patent, Infinite Challenge". Dongsoo Han's current research focus is on developing global indoor positioning and navigation systems. Dongsoo Han is a member of IEEE and IEEE Computer society, and a board member of the ITS Korea society.

Tutorial 2 : The fundamentals of Inertial Navigation System

Speaker: Dr. Valerie Renaudin(IFSTTAR–GEOLOC)

Course Level: Beginner to Intermediate

This course presents the fundamentals of inertial navigation sensors and systems for navigating following an integrated multi-sensors navigation strategy. After the introduction about inertial navigation, accelerometer and gyroscope sensors will be discussed in terms of design, error sources and modeling. The course continues with the presentation of inertial Strapdown mechanization algorithms and the involved geographical frames. Different strategies for mitigating the sensor errors but also integrating inertial sensors with other sensors will be presented and compared in the position, velocity and attitude domains. Concepts will be illustrated in the field of pedestrian navigation. Conclusion will be drawn about future inertial technology developments.

Dr. Valerie Renaudin is a senior researcher at GEOLOC Lab in the French research institute on Transport:IFSTTAR. She received her MSc degree in geomatics engineering from ESGT (France) and her PhD in computer, communication, and information sciences from EPFL (Switzerland). She was technical director at Swiss at developing real time geolocalization solutions with GNSS permanent reference stations and senior research associate at PLAN Group in the University of Calgary (Canada). Her research interests focus on all aspects of GNSS and inertial signals processing for pedestrian navigation. She was recently awarded the Marie Curie Career Integration Grant for her project smartWALK.
