The availability of location information has become a key factor in today's communications
systems allowing location based services. In outdoor scenarios, the mobile terminal position …

Motion tracking based on commercial inertial measurements units (IMUs) has been widely
studied in the latter years as it is a cost-effective enabling technology for those applications …

In this letter we propose a tightly-coupled Extended Kalman Filter framework for IMU-only
state estimation. Strap-down IMU measurements provide relative state estimates based on …

Most ultrawideband (UWB) location systems already proposed for position estimation have
only been individually evaluated for particular scenarios. For a fair performance comparison …

Wearable inertial measurement unit (IMU) sensors are powerful enablers for acquisition of
motion data. Specifically, in human activity recognition (HAR), IMU sensor data collected …

An accurate and reliable Indoor Positioning System (IPS) applicable to most indoor
scenarios has been sought for many years. The number of technologies, techniques, and …

Technological developments over the past two decades have resulted in the development of
more accurate and lightweight low-cost magnetic and inertial measurement units (MIMUs) …

Real-time locating and tracking Technology plays a significant role in location-based IoT
applications. With the extensive installation of WiFi access points, the WiFi based indoor …

We present a new method to accurately locate persons indoors by fusing inertial navigation
system (INS) techniques with active RFID technology. A foot-mounted inertial measuring …

Fifteen years have passed since the publication of Foxlin's seminal paper “Pedestrian
tracking with shoe-mounted inertial sensors”. In addition to popularizing the zero-velocity …
